Question

Calculate the number of molecules of carbon dioxide (CO2) in 4.4 g of carbon dioxide gas.
(Ans. 6.022x1022 mole)​

Answer 1

Answer:

4.4g of co2

c=12 O2=16 so by adding we get 28. so the mass of one co2 molecule is 28. so it is 28g in a mole so if we divide it by 4.4 we get 280/44 =6.36
