Question

How many grams of glucose are dissolved in 500 ml of a 0.50% glucose solution?

Answer 1

A 0.50% glucose solution contains 0.5 grams of glucose per 100 ml of solution.

Use this ratio to find the amount of glucose that is present in 500ml of solution.

$500ml\cdot\frac{0.5gGlucose}{100ml}=2.5gGlucose$

According to this, 2.5g of glucose are dissolved in 500ml of solution.
