chemical formula = ZnCl2
molecular mass = 136 u
no of moles = 34 /136 => 0.25 moles
molecular mass = 136 u
no of moles = 34 /136 => 0.25 moles

chemical formula-ZnCl2
molecular mass=65+2(35.5)u=136u
Given mass = 34 g
Molar mass = 136 u
No : of moles = Given mass ÷ Molar mass
= 34 ÷ 136
= 0.25 moles
