How much dextrose is contained in 2 L of D5W solution?
100 g
150 g
500 g
1,000 g
1,000 g
Rationale: D5W stands for 5% dextrose dissolved in water. w/v% is the number of grams dissolved in 100 mL of solution. Use this proportion to solve: 5 g /100 mL = X g / 2000 mL (since 2000 mL = 2L). By cross-multiplying, you find that 100X = 10,000 and by reducing you find that X = 1,000 g.
