56. Solving a chemistry problem

3. The density of a 5.18% solution of phenol in water is 1.0042 g/cm3. The density of water is 0.9991 g/cm3. Express the composition of the solution in moles of phenol per 1 mol of water and in moles of phenol per 1 liter of solution. What is the specific volume of phenol in solution, if we assume that the specific volume of water does not change during the formation of the solution.
