plz help me fast correct answer i will mark u brainliest

Answer 1

Explanation:

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

Molar mass of O

2

=2×16=32 g

Number of molecules in 32 g oxygen = N

A

Number of molecules in 40 g oxygen =

32

40

×N

A

Given: molecules in 40 g oxygen = molecules of m g carbon dioxide

44

m
