If you administer 5 mL of a 2% solution, how many grams of solute have been given?

To determine how many grams of solute are in 5 mL of a 2% solution, it’s essential to understand what a percentage solution means. A 2% solution indicates that there are 2 grams of solute in every 100 mL of solution.

First, we need to figure out how much solute is in 5 mL of the 2% solution. The calculation involves the relationship between the volume of the solution administered and its concentration.

Using the proportion from the percent concentration:

• In 100 mL of solution, there are 2 grams of solute.

• To find out how many grams are in 5 mL, you can set up a ratio or simply multiply the total grams by the fraction of the volume given.

The math is as follows:

• Calculate the number of grams in 5 mL:

[

\text{grams of solute} = \left(\frac{2 \text{ grams}}{100 \text{ mL}}\right) \times 5 \text{ mL}

]

• This simplifies to:

[

\text{grams of solute} = \frac{2 \times 5
