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?

16.8 g/L.

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,

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