Question

calculate formula mass of HNO^3 CaCl^2. Atomic mass :- H=1, N=14, O=16, Ca=40, Cl=35.5​

Answer 1

Explanation:

HNO3 will be 63

CaCl2 will be 110

Answer 2

Explanation:

1) for HNO3,

mass of HNO3=(1)+(14)+3(16)

=1+14+48=63

2) for CaCl2,

mass of CaCl2=(40)+2(35.5).

=40+71=111

so your answer are 63 and 111
