Question

which of the following is the number of grams of dextrose in 500 ml of dextrose 10% in water (d₁₀w)? 10 g, 50 g, 100 g, 500 g

Explanation:

Step1: Understand the percentage concentration

A 10% dextrose in water ($D_{10}W$) means that there are 10 grams of dextrose per 100 mL of the solution.

Step2: Calculate for 500 mL

First, find out how many sets of 100 mL are in 500 mL: $\frac{500\ mL}{100\ mL} = 5$.
Then, multiply the amount of dextrose per 100 mL (10 g) by the number of 100 mL sets: $10\ g \times 5 = 50\ g$.

Answer:

50 g (corresponding to the option with 50 g)
