What is Molar Mass?

Molar mass is defined as the mass of one mole of a substance. It is expressed in grams per mole (g/mol) and is calculated by summing the atomic masses of all the atoms in a molecule. For C2H4, the molar mass can be determined by adding the atomic masses of two carbon © atoms and four hydrogen (H) atoms.

Calculating the Molar Mass of C2H4

To calculate the C2H4 molar mass, we need to know the atomic masses of carbon and hydrogen. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of hydrogen is approximately 1.008 g/mol. Using these values, we can calculate the molar mass of C2H4 as follows:

Molar mass of C2H4 = (2 × atomic mass of C) + (4 × atomic mass of H)

Molar mass of C2H4 = (2 × 12.01 g/mol) + (4 × 1.008 g/mol)

Molar mass of C2H4 = 24.02 g/mol + 4.032 g/mol

Molar mass of C2H4 = 28.052 g/mol

Therefore, the C2H4 molar mass is approximately 28.052 g/mol.
