Question

what is the mass of 5 mole of chlorine gas. (atomic mass of Cl=35.5u.

Answer 1

1 MOLE OF CI = 35.5 Cu 

     THERE ARE 5 MOLES, THEREFORE 
= > 35 . 5 * 5 
= . 177. 5 u 




_______________________________________________________________________________________________________________________________________





      THEREFORE, THE MASS OF 5  MOLES OF CHLORINE GAS = > 177.5 u 

Answer 2

Molar mass=35.5g
1 mole=35.5g
5 mole=5×35.5g
=177.5g
