A solution contains 30 g of urea dissolved in 470 g of water. What will be the mass% of this solution?
Answers
The mass percent of this solution is 6%.
A solution contains 30g of urea dissolved in 470g of water.
We have to find the mass percentage of this solution.
We know,
- A solution has two components ; solute and solvent.
- The component which presents in solution in lesser amount is solute
- And the other which present is greater amount is solvent.
Concept : mass percent of a solution is the percentage ratio of mass of solute to the mass of solution.
i.e., mass percent of solution = mass of solute/mass of solution × 100
Here, urea is solute and water is solvent.
so the mass of solution = mass of solute + mass of solvent
= 30g + 470g = 500g
mass of solute = 30g
∴ mass percent of the solution = 30/500 × 100 = 6%
Therefore the mass percent of the solution is 6%.
