Complete the table:
Mass Solute Mass Solvent Mass Solution Mass Percent
2.65 g 26.0 g
46.8 g 4.0 %
1.68 g 26.2 g
26.7 g 5.9 %

1.

Mass solution = 28.65 g

Mass percent = 9.14 %

2.

Mass solute = 1.95 g

Mass solution = 48.75 g

3.

Mass solvent = 24.52 g

Mass percent = 6.41 %

4.

Mass solution = 476.8 g

Mass solvent =450.1 g

Explanation:

Hello,

In this case, we define the mass percent as:

Wherein we use the mass of the solute and the mass of the solvent in order to compute it, thus, for each case we have:

1.

Mass solution: 2.65 g + 26.0 g = 28.65 g

Mass percent: 2.62 g / (2.65 g + 26.0 g) x 100% = 9.14 %

2.

Mass solute: 4.0 % x 46.8 g / (1 - 4.0 %) = 1.95 g

Mass solution: 1.95 g + 46.8 g = 48.75 g

3.

Mass solvent: 26.2 g - 1.68 g = 24.52 g

Mass percent: 1.68 g / (1.68 g + 24.52 g) x 100% = 6.41 %

4.

Mass solution: 26.7 g / 5.6 % = 476.8 g

Mass solvent: 476.8 g - 26.7 g =450.1 g
