Question

Which one of these following has sme numbers of molecules as preseny in 11 g of Co2 purification he had made 12 g of product..which of the follpwing is Perce yield

Answer 1

Answer:

Molar mass of carbon dioxide =12+2×16=44 g

Molar mass of O2 =2×16=32 g

Number of molecules in 32 g oxygen = NA

Number of molecules in 40 g oxygen = 32/40×N A

Given: molecules in 40 g oxygen = molecules of m g carbon dioxide 44gm ×NA= 32/40×NA

m/44= 32/40

m=55 g
