What amount of 6% nitroglycerin ointment must be diluted with lanolin petrolatum base to fill an order for 1 pound of 2% nitroglycerin

151.3 grams.

Explanation:

The amount of the dilution can be calculated by the formula as follows;

C₁V₁ = C₂V₂

Here, C₁ = 6% or 0.06, C₂ = 2% or 0.02 and V₂ = 1 pound or 454 grams, the volume V₁ can be calculated by the formula shown above.

.06 × V = .02 × 454

V = 151.3 grams.

Thus, the answer is 151.3 grams.
