Question

What is the mass of co2 which contains the same Number of molecules as contained in 40g of oxygen

Answer 1

Answer:

55g

Explanation:

number of molecules in 40 g of o2 =5×3.011×10^23/2 for co2

mass = molecular weight of co2 / na × number of molecules

mass of co2= 44× 5×3.011 ×10^23/6.022×10^23×2

mass of co2 = 44×5/4= 55g
