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

Nuetrik [128]

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).

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

$Ratio=\frac{24}{15,750000}$

$Ratio=\frac{1}{656250}$

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

Answer:

447.44 is your final answer

Step-by-step explanation:

680 x 0.3 = 204

680 - 204 = 476

476 x 0.06 = 28.56

476 - 28.56 = 447.44

447.44 is your final answer.
