Density is 1.25g/mol ml in 1 litter of solution the amount of solute + solution will be 1250 and as we know water has density of 1g/ml so 1000g of water will be there in 1litter of solution remaining 250 g is soluteNow in 1 litter solution 250g of solute is there or =250/62.5 = 4 mol of solute in 1 litter solutionThus the molarity is 4 Molar
