Answer:
0.35 M
Explanation:
Molar mass of calcium chloride= 40+2(35.5)= 111gmol-1
Mass calcium chloride= 21.84g
Volume of solution= 562.43ml
From
n= CV
But n=m/M
n= number of moles
C=concentration
V= volume of solution in litres
m=mass of substance
M= molar mass of substance
n=21.84/111= 0.197moles
C= 0.197 ×1000/562.43
C= 0.35 M
