A drug advertises that it has 18.7% active ingredient. If the dose is 12 g, how much of the dose is active ingredient?
To find out how much of the dose is the active ingredient, we need to calculate 18.7% of 12 g.
First, convert 18.7% to decimal form by dividing it by 100: 18.7/100 = 0.187
Next, multiply 0.187 by 12 g to find the amount of active ingredient in the dose: 0.187 * 12 = 2.244
Therefore, 2.244 g of the 12 g dose is the active ingredient.
To find out how much of the dose is the active ingredient, we can use the formula:
Amount of active ingredient = (Percentage of active ingredient / 100) * Dose
Given that the percentage of active ingredient is 18.7% and the dose is 12 g, we can plug in the values:
Amount of active ingredient = (18.7 / 100) * 12
Now, we can calculate:
Amount of active ingredient = (0.187) * 12
Amount of active ingredient = 2.244 grams
Therefore, 2.244 grams of the dose is the active ingredient.
