Question

Ibuprofen is the most common pain reliever found in medicines. If Motrin contains 0.8 g of ibuprofen in a 500 mL bottle, what is the concentration of ibuprofen in a bottle of Motrin?

Answer 1

1.6 g/L

Step-by-step explanation:

To calculate the concentration of ibuprofen in a bottle of Motrin, we need to divide the amount of ibuprofen (in grams) by the volume of the bottle (in liters).

First, we need to convert the volume of the bottle from milliliters (mL) to liters (L):

500 mL = 0.5 L

Now we can calculate the concentration:

Concentration = Amount of ibuprofen / Volume of bottle

Concentration = 0.8 g / 0.5 L

Concentration = 1.6 g/L

Therefore, the concentration of ibuprofen in a bottle of Motrin is 1.6 g/L.
