Question

choose a method of calculation dosage and complete the following dosage calculation. order: 2 grams have: 50 milligrams in 3 milliliters give: ________

Explanation:

Step1: Convert grams to milligrams

Since \(1\) gram \( = 1000\) milligrams, for an order of \(2\) grams, we have \(2\times1000=2000\) milligrams.

Step2: Set up proportion

Let \(x\) be the volume to give. We know that the ratio of drug amount to volume is constant. So \(\frac{50\space mg}{3\space mL}=\frac{2000\space mg}{x}\).
Cross - multiply gives \(50x = 2000\times3\).

Step3: Solve for \(x\)

First, calculate \(2000\times3 = 6000\). Then \(x=\frac{6000}{50}=120\)

Answer:

\(120\) milliliters
