Question

Determine the mass by mass percentage and volume percentage concentration of a 100 ml salt solution which contains 15 g salt?​

Answer 1

Explanation:

Solution:- (B) 20%

As we know that,

mass by mass percent=Wt.of salt/Total wt. of salt ×100

Given that:-

Weight of salt = 20 g

Total weight of salt = 100 g

∴ mass by mass percent=20/100×100=20%
