Question

An `NaOH` solution contains 1.90 mol of `NaOH`, and its concentration is 0.555 M. What is its volume?

Answer 1

The volume is `"3.42 L"`.

Explanation:

First rewrite the molarity of NaOH, `"0.555 M"`, as `"0.555 mol/L"`.

Next divide the given moles NaOH by the molarity of the solution in mol/L.

`cancel"1.90mol NaOH"xx("1L NaOH")/(cancel"0.555 mol NaOH")="3.42 L"`
