Answer:
a. 0.50 g, 1.0 g, 1.5 g, 2.0 g, 2.5 g;
g. 0.1 g, 0.5 g, 1.0 g, 1.5 g, 2.0 g
Explanation:
The percent mass is defined as a ratio between the mass of a solute and mass of a solution:
Since solution only consists of a solute and solvent, express its mass as:
Then:
Firstly, solve for how much mass is required to prepare 3.0 %. Let's say, we have x g of the solute:
Similarly, solve for 6.0 %, let's say, we have x g of the solute again:
Hence, masses should be in a range of 0.93 g to 1.91 g.
