Question

if a solution has a concentration of 25 mg/ml, how many grams of the medication are in 600 ml of the solution?

o 12 grams
√ o 15 grams
o 20 grams
o 10 grams

Explanation:

Step1: Calculate mass in milligrams

Use the formula $m = C\times V$, where $C = 25\ mg/ml$ and $V=600\ ml$. So $m = 25\ mg/ml\times600\ ml=15000\ mg$.

Step2: Convert milligrams to grams

Since $1\ g = 1000\ mg$, then $m$ in grams is $\frac{15000\ mg}{1000}=15\ g$.

Answer:

15 grams
