One molecule of a compound weighs 2.03x10-22 g. what is the molar mass of that compound?

The molar mass of the given compound is .

Further Explanation:

Molar mass:

The molar mass is the summation of masses of all atoms or molecule present in the 1 mole of compound. In other words, molar mass of a compound is the ratio of mass of compound in grams to the number of moles present of that compound. The S.I unit of molar mass is gram per mol or g/mol.

Mass of one molecule of a given compound is .

According to Avogadro's number, the number of atoms or molecules present in the 1 mole of a substance is .

Therefore, to calculate the mass of 1 mole of atoms, we have to multiply the mass of one molecule with the number of molecules present in 1 mole of given compound that is .

The calculation for molar mass gives as follows:

The value mass of 1 mole of given molecule is 122.2 g/mol.
