Q. 9.54 - An Introduction to General, Organic, and Biological Chemistry

Question

A patient received $2.0 g of NaCl$ in $8 h$. How many milliliters of a $0.90\% (m/v)$$NaCl$ (saline) solution were delivered?

Step-by-Step Solution

Answer

$222 \mathrm{ml}\text{ solution }$of a $0.90\% (m/v)$ saline solution were delivered.

Step1: Introduction.

A saline solution is a salt as well as water solution. This same level of sodium in salt solution is $0.9$percent sodium chloride (salt), which really is comparable to the sodium concentration in the blood and tears.

Step2: Given Information.

Given:

A patient having $2.0 g of NaCl$ in $8 h.$

To know the milliliters of $0.90\% (m/v) NaCl$ saline solution.

Step3: Explanation.

The $0.90\% (m/v)$ saline solution is written as,

$100 \mathrm{ml}\text{ solution }=0.90 g \mathrm{NaCl}$

$\frac{0.90 g \mathrm{NaCl}}{100 \mathrm{ml}\text{ solution }}\text{ and }\frac{100 \mathrm{ml}\text{ solution }}{0.90 g \mathrm{NaCl}}$

Using conversion, Find the volume from grams of solute is as,

$$\begin{gathered} =2.0 \mathrm{g} \mathrm{KaCl}\times \frac{100 \mathrm{ml}\text{ solution }}{0.90 \mathrm{g} \mathrm{AaCl}} \\ =222 \mathrm{ml}\text{ solution } \end{gathered}$$
