Question

Calculate the number of moles in the following?A) 46 g ofNa B) 60g OF Ca Given atomic mass Na= 23 g and Ca= 40g​

Answer 1

Answer:

Explanation:

(ii)46g of Na , The no. of moles=Mass of Na in grams/Gram atomic mass =m/M=(46g)/(23g)=2mol

(iii)60g of Ca The no. of moles=Mass of Ca in grams/Gram atomic mass=m/M=(60g)/(40g)=1.5mol
