Question

if 40 gram of Sodium Hydroxide is present in 100 gram of water when what is the molarity of the solution​

Answer 1

Answer:

The molar mass of NaOH is 40 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 =40g/mol40g=1mol

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

M=1L1mol=1M
