Answer:
Compute for the molar mass of NaOH by adding the atomic masses of the component atoms. 1 mole of Na has a mass of 23 g; 1mole of oxygen has a mass of 16 g; and 1 mole of H has a mass of 1g. The masses sums up to 40g.
Multiply 40 g/ mole by 0.05 moles / liter. The product is 2 g/L.
Dissolve 2g of NaOH in a liter of water.
The resulting solution has a concentration of 0.05 M of NaOH or 0.05 moles per liter of NaOH.
