# Question #414f4

##### 1 Answer

#### Explanation:

**Molarity** is simply a measure of a solution's concentration in terms of the **number of moles of solute** it contains in **one liter**.

This means that if you take exactly

In this case, your solution must have a molarity of **every liter** of this solution will contain **moles** of calcium chloride, your solute.

Your solution must have a volume of

#6.5 color(red)(cancel(color(black)("L solution"))) * "0.290 moles CaCl"_2/(1color(red)(cancel(color(black)("L solution")))) = "1.885 moles CaCl"_2#

In order to convert the number of moles to *grams*, use the 8*molar mass** of calcium chloride

#1.885 color(red)(cancel(color(black)("moles CaCl"_2))) * "110.98 g"/(1color(red)(cancel(color(black)("mole CaCl"_2)))) = color(green)(bar(ul(|color(white)(a/a)color(black)("210 g")color(white)(a/a)|)))#

The answer is rounded to two **sig figs**.
