A pharmacy technician has a 70% solution of dextrose in stock. How many grams of dextrose are in 400 mL of this solution?
140 grams
280 grams
420 grams
560 grams
280 grams
Rationale: To calculate the amount of dextrose in 400 mL of the stock 70% solution, we first must understand that 100 mL contains 70 grams of dextrose. Therefore 400 mL would contain 70 x 4, or 280 grams of dextrose.
