Question 7
Dymelor 0.75 g is ordered. Scored tablets are labeled 500 mg. each. How many tablets will you,

Answer 1

1) 3.2 mL
- (2 mL / 50 mg) × 80 mg = 3.2 mL

2) 72 mL more
- 4 oz = 4 × 30 mL = 120 mL; 120 − 48 = 72 mL

3) 400 ounces
- 12 × 1000 mL = 12,000 mL; 12,000 ÷ 30 mL/oz = 400 oz

4) 12 mL = 2.4 teaspoons (≈ 2.5 tsp if rounding)
- (4 mL / 2 mg) × 6 mg = 12 mL; 12 mL ÷ 5 mL/tsp = 2.4 tsp

5) 20 mL
- (10 mL / 40 mg) × 80 mg = 20 mL

6) Net gain 420 mL
- Intake = 8 × 8 oz = 64 oz = 64 × 30 mL = 1920 mL; 1920 − 1500 = +420 mL

7) 1.5 tablets (one and a half tablets)
- 0.75 g = 750 mg; 750 ÷ 500 = 1.5 tablets
