molar mass of calcium chloride= 110.98
molarity= 10×10^-3M
volume=250×10^-3L
molarity,= no of moles /volume of solution in litres
no of moles= molarity × volume of solution in L
substituting we get
no of moles= 25×10^-4
no of moles = given mass / molecular mass
given mass= molecular mass×no of moles
= 110.98×25×10^-4
=2.7g
