# What mass of #NaOH# is contained in 250.0 mL of a 0.400 M sodium hydroxide solution?

##### 2 Answers

#### Explanation:

3.998 grams NaOH

#### Explanation:

The Molarity of a solution is determined by the comparison of the moles of the solute compared to the volume of the solution in liters.

The equation of the formula is

In order to find the mass we first need to solve for the moles.

M = 0.400

moles = ?

L = 250.0 mL or 0.25 L

Now we can calculate the grams be converting moles to grams.

3.998 grams NaOH
