Question

b. Determine the molecular formula of a molecule with an empirical formula NH2and a molar mass of 32 g/mol.

Answer 1

i'm taking this lesson now, so imma help u ( if u need anything else ask me)

so given Molar mass= 32 g/mol
molar mass= (empirical formula) n
32 = (14x1 + 2x1) n
32 = 16 n , so n= 2
so, molecular formula= N2H4
