Answer: About 16.5 grams
Explanation:
To find out how many grams of the pure drug are contained in 76 milliliters, you can set up a proportion based on the given information:
33 grams / 152 milliliters = x grams / 76 milliliters
To solve for x (the number of grams in 76 milliliters), you can cross-multiply and then divide:
33 * 76 = 152 * x
2508 = 152x
Now, divide both sides by 152 to isolate x:
x = 2508 / 152
x ≈ 16.5 grams
So, there are approximately 16.5 grams of the pure drug contained in 76 milliliters.
