To make a saturated solution 40 g of a salt is added to 200 g of water at 300 K. The concentration of the solution in terms of mass by mass percentage is
Answers
Answer:
16.67%
Explanation:
Amount of solute: 40g
Amount of solvent: 200g
Mass % = 100 x (Amount of solute / mass of solution)
= 100 x (40/200+40)
= 100 x 40/240
= 16.67% Approx.
6.67 percent is the answer.
Amount of solute = 40g
Amount of solvent = 200g
Mass % = 100 x (Amount of solute / mass of solution)
= 100 x (40/200+40)
= 100 x 40/240
= 16.67% Approx.
Mass Percentage Formula
Mass percent is the mass of the element or solute divided by the mass of the compound or solute. The result is multiplied by 100 to give a percent.
The formula for the amount of an element in a compound is:
mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100
The formula for a solution is:
mass percent = (grams of solute / grams of solute plus solvent) x 100
or
mass percent = (grams of solute / grams of solution) x 100
The final answer is given as %.
