Question

A solution contains 11% by mass of sodium chloride. This means that ________

A) there are 11 g of sodium chloride in in 1.0 mL of this solution
B) 100 mL of the solution contains 11 g of sodium chloride
C) the density of the solution is 11 g/mL
D) 100 g of the solution contains 11 g of sodium chloride

Answer 1

The solution contains 11% sodium chloride, which means that 100 mL of the solution contains 11 g of sodium chloride.

Step-by-step explanation:

The correct answer is B) 100 mL of the solution contains 11 g of sodium chloride.

When a solution is described as having a certain percentage by mass, it means that for every 100 grams of the solution, there are 11 grams of sodium chloride. This is equivalent to saying that 100 mL of the solution contains 11 grams of sodium chloride.

For example, if you had 200 mL of the solution, you could calculate the amount of sodium chloride by using the proportion: (11 g/100 mL) x (200 mL) = 22 g of sodium chloride.
