Question

Find the molecular mass of the following compounds.

a) KOH


b) NaHCO3
c) CaCl2

(Given: Atomic mass K = 39 u , O = 16 u , H= 1 u , Na= 23 u , C= 12 u , Ca = 40 u , Cl = 35.5 u)​

Answer 1

Answer:

Koh = 56

Nahco3 =74

Cacl2 = 110

Answer 2

Answer:

à) KOH = 39+16+1

= 56U

B)NaHCO3=23+1+12+(16*3)

= 36+48=84U

C) CaCl2 = 40+(35.5*2)

= 40+71=111u
