Question

Determine the mass (in g) of each NaCl solution that contains 1.1 g of NaCL

part a ) 0.050 % of NaCl by mass

part b) 1.28 % of NaCL by mass

part c) 9.24 % NaCl by mass

Answer 1

Ans :

m/m % = ( mass of NaCl / mass of solution ) x 100

so here , putting values :

Part a :

0.050 % = ( 1.1 g / m ) x 100

m = 2200 g

Part b :

1.28 % = (1.1 g / m ) x 100

m = 85.9 g

Part c :

9.24 % = ( 1.1 g / m ) x 100

m = 11.9 g
