##### 2 Answers

#### Explanation:

Molarity = molar concentration = how many moles in

(I've used the rounded molar masses)

So

#### Explanation:

Molarity is defined by the following equation

So, we first need to convert

So,

We can also convert the amount of milliliters to liters.

So,

Now, we have the desired units, we can plug it into the molarity equation.

We can also write it as
