Question

Morality and molarity of a solution of a liquid mws 50 in aqua solution is 9 and 10 respectively what is the density of solution

Answer 1

This means that 10 moles of the compound are present in 1000 + 500 = 1500 g of solution i.e. 1 mole per 150 g. Since 1 mole of the solute is found in 150 g or 125 ml of the solution, the density of the solution would be 150 g/125 mL = 1.2 g/mL.
