40.00 grams of NaOH is added into distilled water and diluted with water to 1000mL of final volume. What is the final concentration of the NaOH

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
