There are two quantities of salt solution: 80g and 120g. In the first solution there are 12g of salt, in the second solution there are 15g of salt. What is the concentration (in percent) of salt in each solution? What would be the concentration if we were to mix these solutions?

80 g........12 g salt
120 g........15 g salt

I. 12/80=0.15=15/100= 15 %
II. 15/120=0,125= 125/1000=12,5 /100=12,5 %

if you werw to mix these solutions
120+80=200 g solutions
12+15=27 g salt
27/200=13,5/100= 13.5 %

The concentration (in percent) of salt in each solution is 15% and the concentration, if we were to mix these solutions, is 13.5%.

What is concentration?

Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume. Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.

80 g........12 g salt

120 g........15 g salt

I. The concentration (in percent) of salt in each solution.

12/80=0.15=15/100= 15 %

II. The concentration if we were to mix these solutions.

120+80=200 g solutions

12+15=27 g salt

27/200=13,5/100= 13.5 %
