How many grams of 2% silver nitrate ointment will deliver 1 g of the active ingredient
50 g
To determine the answer, we'll need to use the concept of percent composition. Percent composition refers to the percentage of a specific substance within a mixture. In this case, we're given that the silver nitrate ointment is 2% silver nitrate.
To calculate the grams of silver nitrate needed to deliver 1 g of the active ingredient, we can set up a proportion by comparing the percentage of the active ingredient to the total weight of the ointment.
Let's assume the total weight of the ointment is "x" grams. Since the silver nitrate ointment is 2% silver nitrate, we can write the equation:
(2 g / 100 g) = (1 g / x g)
To solve for "x," we can cross-multiply and solve the equation:
2g * x = 1g * 100g
2x = 100
Dividing both sides of the equation by 2 gives us:
x = 50
Therefore, the total weight of the ointment needed to deliver 1 g of the active ingredient is 50 grams.
