Question

What volume of 1.5M NaOH is needed to provide 0.75 mol of NaOH?

Answer 1

We require an half a litre volume of the given solution........and gets a `0.50*L` volume...........

Explanation:

We divide the molar quantity by the concentration, i.e.

`(0.75*cancel(mol))/(1.50*cancel(mol)*L^-1)=(0.50)/(L^-1)=0.50*1/(1/L)=0.50*L`
