Notes on using the Molar Mass Calculator

Chemical formulas are case-sensitive.
Enter subscripts as elementary numbers.
The converter uses a simple dot instead of using a midpoint typographic dot (·) in formulas for adduct molecules, such as water of hydration.
Instance: type CuSO4.5H2O instead of CuSO₄·5H₂O.

Calculating the Molar Mass

Mole

All substances consist of atoms or molecules. In chemistry, it is important to measure their amounts accurately. The mole is used to express the amounts of reactants and products of chemic reactions. The mole, symbol mol, is the SI unit of the corporeality of substance. Ane mole contains exactly 6.02214076×10²³ elementary entities. This number is the stock-still numerical value of the Avogadro constant, N_A, when expressed in the unit of measurement mol⁻¹ and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified unproblematic entities. An elementary entity may be an atom, a molecule, an ion, an electron, whatever other particle or specified group of particles.

Avogadro constant N_A = 6.02214076×10²³ mol⁻¹

In other words, the mole is the amount of substance equal in mass to the combined mass in atomic mass units of the atoms of molecules of the substance multiplied by the Avogadro constant or Avogadro number. The mole as the unit of measurement of measurement for the corporeality of substance is one of the seven base units of the International System of Units (SI). Its symbol is mol. Ane mole of pure carbon-12 has a mass of exactly 12 grams.

Molar mass

The molar mass is a physical property, which is defined as the mass of a substance divided by its corporeality of substance in moles. In other words, information technology is the mass of one mole of a particular substance. In SI, the unit for tooth mass is kg/mol. However, chemists almost e'er express molar masses in g/mol for convenience.

Molar mass = grams/mole

Burning is a high-temperature exothermic redox chemical reaction

Tooth Masses of Elements and Compounds

Compounds are substances consisting of several different atoms held together by chemical bonds. For case, the following substances that can exist found in every kitchen are compounds:

salt (sodium chloride) NaCl
sugar (sucrose) C₁₂H₂₂O₁₁
vinegar (acetic acrid solution) CH₃COOH

The tooth mass of elements in grams per mole is numerically equal to their diminutive mass in unified atomic mass units (u) or daltons (Da). The molar mass of compounds is equal to the sum of molar masses of the atoms which class the compound. For example, the molar mass of water (H₂O) is approximately i × two + 16 = xviii g/mol.

Molecular Mass

Molecular mass (older name molecular weight) is the mass of a molecule calculated as the sum of the mass of each atom in the molecule multiplied by the number of atoms of that element in the molecule. Molecular mass is a dimensionless quantity numerically equal to the molar mass. Though molecular and atomic mass values are dimensionless, they are given the unit dalton (Da) or unified atomic mass unit (u), which is approximately the mass of a single proton or neutron and is numerically equivalent to 1 g/mol.

Calculating the Molar Mass

The molar mass of a substance is calculated using three steps:

Finding the atomic masses of elements in the periodic tabular array.
Counting the number of atoms of each chemical element in the compound.
Finding the tooth mass by means of computing the sum of the atomic weight of the atoms, which form the chemical compound multiplied by their numbers.

For example, let us calculate the molar mass of the acetic acid

CH₃COOH

It contains:

two atoms of carbon
4 atoms of hydrogen
ii atoms of oxygen

Now, the adding:

Carbon C = two × 12.0107 grand/mol = 24.0214 g/mol
Hydrogen H = 4 × 1.00794 m/mol = 4.03176 g/mol
Oxygen O = 2 × 15.9994 g/mol = 31.9988 g/mol
Tooth mass = 24.0214 + 4.03176 + 31.9988 = 60.05196 g/mol

Our estimator does the same adding. You can enter the formula and check.

This online unit converter allows quick and authentic conversion between many units of measure, from i system to another. The Unit of measurement Conversion folio provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in unlike units.

Y'all can use this online converter to catechumen betwixt several hundred units (including metric, British and American) in 76 categories, or several thousand pairs including acceleration, surface area, electrical, energy, force, length, light, mass, mass flow, density, specific book, power, pressure level, stress, temperature, time, torque, velocity, viscosity, volume and capacity, book menstruum, and more.
Annotation: Integers (numbers without a decimal period or exponent annotation) are considered accurate upwardly to fifteen digits and the maximum number of digits after the decimal signal is 10.

In this calculator, E notation is used to represent numbers that are also small or too large. E notation is an alternative format of the scientific notation a · 10^x. For example: one,103,000 = 1.103 · ten⁶ = 1.103E+6. Here E (from exponent) represents "· 10^", that is "times ten raised to the power of". E-notation is commonly used in calculators and by scientists, mathematicians and engineers.
