What is the mass of one molecule of cortisone

The mass of one molecule is 360.45g/mol

The formula for Cortisone is C₂₁H₂₈O₅.

The molar mass (mass of one molecule) would be the sum of the atomic mass of all the elements that make up Cortisone

∴ mass of one molecule of Cortisone = [ (12.01 * 21) + (1.00 * 28) + (15.999 * 5) ]g/mol

= (252.21 + 28 + 79.995)

≈ 360 g/mol

That value is due to rounding off. The known accurate value is 360.45 g/mol
