Question

Calculate the number of moles in 22g of CO2 (C=12u , O=16u)

Answer 1

Answer:

answer is 4.5 mole because in 1 mole there is 2044 gram of carbon dioxide therefore in 22 gram it will be point 5 mod

Answer 2

Answer:

GMM mass of CO2 is 12 + 32 g = 44g

So, 44 g of CO2 contains 1 mole of CO2

So, 22 g of CO2 contains 0.5 mole of CO2. (Apply unitary method)
