Calculate W/V% of concentration of solution prepared by dissolving 15 gram glucose in 90 gram of water density of water is 1.2g/ml

Answer 1

The total weight of the solution after mixing the glucose and water is:

15 g + 90 g = 105 g

If the resulting solution has a density of 1.2 g/mL, then the volume of the solution is:

105 g × (1 mL / 1.2 g) = 105 mL

So the weight per volume (w/v %) of gluose is:

15 g / 105 mL = 0.142 g / mL or 14.2%
