How many grams of dextrose are contained in 400 mL of 70% dextrose solution?

  1. 120

  2. 280

  3. 400

  4. 700

The correct answer is: 280

To determine the grams of dextrose in 400 mL of a 70% dextrose solution, we first need to calculate the amount of dextrose in the solution. 70% of the 400 mL solution is dextrose, so we can calculate it as follows: 70% of 400 mL = 0.70 * 400 mL = 280 grams Therefore, there are 280 grams of dextrose in 400 mL of the 70% dextrose solution, making option B the correct answer.
