Question

6. If you need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL, what is the ratio strength (w/v)?

Answer 1

1 : 656250

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).

`Ratio=\frac{\text{Total wight of tablets}}{\text{Total volume}}`

`Ratio=(24)/(15,750000)`

`Ratio=(1)/(656250)​`

Therefore, the ratio strength (w/v) is 1 : 656250.
