Question

calculate the dosage (in milliliters). express your answer to the nearest tenth. assess your answer to determine if it is logical. a dosage of 130 mg has been ordered. the solution strength is 100 mg per ml.

Explanation:

Step1: Set up the proportion

We know that the solution strength is 100 mg per 1 mL. Let $x$ be the volume in mL for 130 mg. The proportion is $\frac{100\ mg}{1\ mL}=\frac{130\ mg}{x\ mL}$.

Step2: Cross - multiply and solve for $x$

Cross - multiplying gives us $100x = 130\times1$. Then $x=\frac{130}{100}=1.3$.

Answer:

$1.3$
