WebMolarity = number of moles of solute volume of the solution in L. So, 10 M = number of moles of solute 0.05. number of moles of solute = 10×0.05 = 0.5 mol. amount of CH3COOH present = 0.5×60 = 30 g. (c) 60% (w/w) means 60 g of solute is present in 100 g of solution. So, 50 g of solution will contain 60 100×50 = 30 g.
