Question

24. A solution contains 40g of
salt in 360g of water. Calculate
the concentration by mass
percentage of solution
O A) 4 %
O B) 6 %
O c) 10%
OD) 9%​

Answer 1

Answer:

10%

Explanation:

Given,

mass of common salt (solute) = 40g

mass of water(solvent) =360g

so the mass of total solution will be 360+40

=400g

we know,

mass of solute/mass of solution×100

=40/400×100

=10 percent....

Answer 2

Answer: c ) 10%

Explanation:

The mass of salt = 40

Mass of water = 360

Mass % .= mass of solute / mass of solute + mass of solvent ×100

= 40/400 ×100

= 10%
