what is the concentration of solution made by dissolving 158 grams of sugar in 173 grams of water?

Sagot :

To solve the concentration of solution by percent by mass (since it is not specified which concentration we should use, so I assume it was percent by mass), we write: (158 g Sugar/(173 g + 158 g) sol'n) × 100% = 47.73% weight/weight.
