Moles to grams and grams to moles

A mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of substance that contains as many entities (atoms, molecules, etc.) as there are in 12 grams of carbon-12.

To convert moles to grams, use the formula: grams = moles × molar mass.

The molar mass of KMnO4 is approximately 158.04 g/mol.

To convert grams to moles, use the formula: moles = grams / molar mass.

The molar mass of calcium (Ca) is approximately 40.08 g/mol.

75 grams.

At standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters.

The molar mass of water is approximately 18.02 g/mol, so there are about 2.78 moles in 50 grams.

Avogadro's number (6.022 x 10^23) is the number of atoms, molecules, or particles in one mole of a substance.

To find the number of moles in a solution, use the formula: moles = concentration (mol/L) × volume (L).
