Answer:
8.0 g of glucose
Explanation:
Step 1: Given data
- Volume of solution: 399 mL
- Concentration of glucose: 2.0%(m/v)
Step 2: Calculate the mass of glucose in 399 mL of a 2.0%(m/v) solution
The concentration of the solution is 2.0%(m/v), that is, there are 2.0 grams of glucose per 100 mL of solution.
399 mL × 2.0 g/100 mL = 8.0 g
