Answer:

The molar mass of NaOH is 40.00 g/mol.

The number of moles of NaOH is equal to the ratio of its mass to molar mass.

The number of moles of NaOH =

40 g/mol

40 g

=1,000 mol

The molarity of NaOH solution is the ratio of number of moles of NaOH to total volume of solution in L.

M=

1 L

1 mol

=1 M
