Question

find the number of moles in 10 gm of co2

Answer 1

_______________________________________________________________1 mol = 44g 

44g = 1mol 

1g = 1 /44 mol

10g = 10 /44 mol

10g = 0.22 mol 
___________________________________________________________

Answer 2

Molar mass of CO₂ = 12+2(16)=12+32=44g
Number of moles in 10g of CO₂= Given mass/molar mass
=10/44
=0.227 mole
Therefore, there are 0.227 moles in 10g of CO₂.
