What volume of 3.00 M NaOH (40.0 g/mol)contains 0.150 mole of NaOH?

Question

Quizplus · Accepted Answer

First, we need to calculate the mass of 0.150 moles of NaOH:

0.150 mol NaOH x 40.0 g/mol = 6.00 g NaOH

Next, we can use the formula:

M = moles of solute / volume of solution (in L)

We rearrange this formula to find the volume of solution:

volume of solution = moles of solute / M

Substituting the given values:

volume of solution = 0.150 mol / 3.00 mol/L = 0.0500 L = 50.0 mL

Therefore, the best choice is B) 50.0 mL.
