obtain Males of Subst a the Lallowi what

Solution

Moles = given mass/molar mass

So

A 7.17g of C with molar mass 12

Moles = 7.17/12 = 0.5975 moles

B 4.02 g of Cl₂ with molar mass 71

Moles = 4.02/71 = 0.0566 moles

C 78g of C₄H₁₀ with molar mass of 58

So moles = 78/58 = 1.34 moles

D 73.5g of Al₂(CO₃)₃ with molar mass 234

So moles = 73.5/234 = 0.3141 moles
