Question

If a horse is given 825 mL of a 10% solution of guaifenesin, the amount in grams of guaifenesin given is:

A. 0.825 g
B. 8.25 g
C. 82.5 g
D. 825 g

Answer 1

To find the mass of guaifenesin in 825 mL of a 10% solution, multiply the volume by the percentage in decimal form (0.10), yielding 82.5 grams.

Step-by-step explanation:

The student is given 825 mL of a 10% solution of guaifenesin. To calculate the amount of guaifenesin in grams, you need to translate the percentage solution into an actual quantity. Since 10% solution means there are 10 grams of the solute in every 100 mL of solution, one can multiply the volume of the solution by the percentage (in its decimal form) to find the mass.

Here are the calculations:

1. Convert the percentage to a decimal: 10% equals 0.10.
2. Multiply the volume of the solution by the decimal percentage: 825 mL × 0.10 = 82.5 grams.

Therefore, the amount of guaifenesin given is 82.5 grams, which corresponds to option C.
