Question

How many molecules of CO 2 are equivalent to 112 g CO 2 ?

Answer 1

Answer:

Explanation:

CO2=1.53x10^2

Answer 2

Answer:

N(CO2) = n(CO2) x Avogadros constant

n(CO2) = mass(CO2)/Molar mass(CO2) = 112/44 = 2.5454….

N(CO2) = 2.545454… x (6.02 x 10^23) = 1.5323636 x 10^24

Explanation:

Therefore, the number of CO2 molecules in 112 g of CO2 = 1.53 x 10^24 molecules (Significant figures)
