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

Sol. 450 ml there is LiCl 200 g

Sol. 1000 ml there is LiCl 200/450×1000

= 444.44 g

Molar = g/molar mass = 444.44/42.394 = 10.48 M
