Question

An analytical chemist wants to make 750.0 mL of a 6.00 M solution of sodium hydroxide. What mass of NaOH will the chemist need to make this solution?{Ans. ~ mass (g) = 180 g NaOH} Write the set up of the calculation that leads to the answer.

Answer 1

So,

Given that:

We could replace the values of the problem to obtain:

To find the mass, multiply by the molar mass of NaOH:

The answer is 180gNaOH.
