Question

solution is prepared by adding 4g of sugar to 16 g of water. Mass % of the sugar in solution is

Answer 1

Answer:

mass percent of solute is = mass of solute / mass of solution× 100

Explanation:

mass of solute = 4g

mas of solvent = 16g

mass of solution = (4+16)g = 20g

mass of % of solute = 4/20× 100

= 20 g

so , here is ur ans.

Answer 2

Given :

mass of sugar = 4 g

Mass of water = 16 g

To Find :

Mass percentage of sugar in solution

Solution :

We know the formula for mass percentage is

Mass percentage = (solute’s mass ÷ mass of solution) x 100%

Here, mass of solute (sugar) = 4 g

         mass of solution = mass of water + mass of sugar

                                     = (16 + 4) g

                                     = 20 g

∴ Mass percentage of sugar in the solution = $\frac{4}{20}$ × 100%

                                                                        = 20%

Therefore, The Mass percentage of sugar in the solution is 20%.
