Question

What is the percent by mass concentration of 1000 ml of a solution (d=1.5 g/ml) that contains 50 g of solute in it?

Answer 1

Answer: The percent by mass concentration is 33.3 %

Step-by-step explanation:

Mass percent is the ratio of mass of solute to the mass of solution in terms of percentage.

mass of solute = 50 g

mass of solution =
`{\text {density of solution}}* {\text {volume of solution}}=1.5g/ml* 1000ml=1500g`

Mass percentage =
`(50g)/(1500g)* 100\%=33.3\%`

Thus percent by mass concentration of 1000 ml of a solution (d=1.5 g/ml) that contains 50 g of solute in it is 33.3 %
