Lesson: Converting between Units of Concentration Chemistry 13e • AP Edition • Modern Chemistry

Chemistry

In this lesson, we will learn how to convert between concentration units quantifying solutes by moles or mass and solvents by mass or volume.

Worksheet: 2 Questions

Q1:

The level of mercury in a stream was suspected to be above the minimum considered safe (1.0 part per billion by weight). An analysis indicated that the concentration was 0.72 parts per billion. Assuming a density of 1.0 g/mL, what is the molarity of mercury in the stream?

Q2:

Which of the following could not be a unit of chemical concentration?
