Answer:
1 : 656250
Step-by-step explanation:
It is given that we need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL.
Tablets = 8
Weight of each tablet = 3 mg
Total wight of tablets = 8 × 3 = 24 mg
Total volume = 15,750 mL.
1 mL = 1000 mg
Total volume = 15,750000 mg
We need to find the ratio strength (w/v).
[tex]Ratio=\frac{\text{Total wight of tablets}}{\text{Total volume}}[/tex]
[tex]Ratio=\frac{24}{15,750000}[/tex]
[tex]Ratio=\frac{1}{656250}[/tex]
Therefore, the ratio strength (w/v) is 1 : 656250.
