Post by: Taylor14 on Dec 18, 2014
1. A 2.5% solution concentration signifies that there are ___2.5g____of solute in every 100g of solution.

2. Therefore, when the mass percent concentration is expressed as a ratio of solute mass over solution mass, it would be__.025____

3. A solution mass of 1 kg is __10______times created than 100g, thus the mass of KI in a kilogram of a 2.5% KI solution would be_____

1000
2.5g/100g
100
10
2.5g/1g
2.5g
25g
2.5cg/g
2.5cg
25cg
