Description : a) 110 g of salt is present in 550g of solution. Calculate the concentration of solution. b) 10 ml of H2SO 4 is dissolved in 90 ml of H2O. Calculate the concentration of solution. -Chemistry
Last Answer : The concentration of salt is determined by the division of mass of the solute by the mass of the solution and the percentage is obtained by multiplying the value by 100. The quotient of the division of 110 by 550 is 0.2 here. So after multiplying it with 100, it is 20%. So the concentration is 20%.
Description : The concentration of a salt solution in terms of mass by mass percentage is 20 and the mass of the solution is 550 g. Determine the mass of solute present in the solution. -Chemistry
Last Answer : Mass by mass percentage = 20% Mass of solution= 550gram Mass of solute/mass of solution multipled by 100 Therefore, 20/100 = 1/5 Hence, Mass of solute=Mass of solution/5 = 550gram/5 = 110Gram Therefore, The mass of solute is 110gm
