Question 14
H

A student mixes 20.0 cm3\mathrm{cm^{3}}cm3 of a salt solution with a concentration of 50.0 g/dm3\mathrm{g/dm^{3}}g/dm3 and 30.0 cm3\mathrm{cm^{3}}cm3 of a solution of the same salt with a concentration of 10.0 g/dm3\mathrm{g/dm^{3}}g/dm3.

What is the concentration of the salt in the mixture?

[1]
A

13.0 g/dm3\mathrm{g/dm^{3}}g/dm3

B

26.0 g/dm3\mathrm{g/dm^{3}}g/dm3

C

30.0 g/dm3\mathrm{g/dm^{3}}g/dm3

D

60.0 g/dm3\mathrm{g/dm^{3}}g/dm3
