Question

Determine the mass by mass percentage concentration of a hundred grams salt solution which contains 20 gram salt...​

Answer 1

Answer:

20%

Explanation:

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%
