Question

Nora stirs one teaspoon, about 4.2 g, of sugar into her mug, which holds about 0.25 L of tea. What is the concentration of sugar in Nora’s tea?

Answer 1

16.8 g/L.

Step-by-step explanation:

Given that,

Mass of sugar, m = 4.2 g

Volume of tea, V = 0.25 L

We need to find the concentration of sugar in Nora's tea.

Here, 4.2 g is the mass of solute and 0.25 L is volume of the solution.

We know that,

`\text{Mass concentration}=\frac{\text{Mass of solute}}{\text{Volume of solution}}\\\\C=(4.2\ g)/(0.25\ L)\\\\C=16.8\ g/L`

So, the concentration of sugar is 16.8 g/L.
