Question

Calculate the molecular formula of a compound with the empirical formula CH2O and a molar mass of 150g/mol .

Answer 1

Answer:

Empirical formula = CH2O

Empirical formula mass

= 12g/mol + 2 g/mol + 16g/mol = 30 g/mol

=Molecular formula mass/Empirical formula mass

=(60 g/mol)/(30 g/mol)

=2

Molecular formula =2×CH2O=C2H4O2

Answer 2

Answer:

empirical formula =CH20

mass = 12g/ Mol + 2g/ Mol + 16g/ Mol = 30g/ Mol

molecular formula mass / = (60g/ Mol) / (30g/mol)

= 2

molecular formula = 2 × CH20 = C2H402
