Mass of 1.5 × 10^26 molecules = 16000g
Mass of 1 molecule = 16000g / 1.5 × 10^26
Mass of 1 mole (6.022× 10^23) molecules
= 16000g × 6.022 × 10^23 / 1.5 × 10^26
= 64.23467 g
∴ Molecular mass of the substance is 64.23467 .
Mass of 1 molecule = 16000g / 1.5 × 10^26
Mass of 1 mole (6.022× 10^23) molecules
= 16000g × 6.022 × 10^23 / 1.5 × 10^26
= 64.23467 g
∴ Molecular mass of the substance is 64.23467 .
