A If you dissolve 10 grams of sugar in 30 grams of water, you will make grams of % sugar syrup.

40 grams of 25% sugar syrup

Explanation:

We are given;

Mass of sugar (solute) is 10 g

Mass of water (solvent) is 30 g

Therefore;

Mass of the solution = 10 g + 30 g

                                  = 40 g

% of the solute = (Mass of solute ÷ Mass of solvent) × 100%

                         = (10 g ÷ 40 g) × 100%

                         = 25%

Therefore, the mixture will be 40 g of 25% sugar syrup
