Question

what is the molarity of a 2.4 l solution with 1.2 moles of nitric acid (hno₃)?

• your answer should have two significant figures (round your answer to two decimal places).
• do not include units in your response.

provide your answer below:

Explanation:

Step1: Recall the formula for molarity

Molarity ($M$) is calculated as $M=\frac{n}{V}$, where $n$ is the number of moles of solute and $V$ is the volume of the solution in liters.

Step2: Substitute the given values into the formula

Given $n = 1.2$ moles and $V=2.4$ L. Then $M=\frac{1.2}{2.4}$.

Step3: Calculate the value

$\frac{1.2}{2.4}=0.5$. Rounding $0.5$ to two decimal places (while still having two significant figures) gives $0.50$.

Answer:

0.50
