Question

question 31 (1 point) listen a solution has 2.3moles of nacl per 1.0 liter of solution. what is its molarity? 1) 2.3m 2) 1.0m 3) 2.3 millimolar 4) none of the above.

Explanation:

Step1: Recall Molarity Formula

Molarity ($M$) is defined as moles of solute per liter of solution, so the formula is $M = \frac{\text{moles of solute}}{\text{volume of solution (in L)}}$.

Step2: Plug in Values

Given moles of $\text{NaCl} = 2.3$ mol and volume of solution $= 1.0$ L. Substitute into the formula: $M = \frac{2.3\ \text{mol}}{1.0\ \text{L}} = 2.3\ \text{M}$.

Answer:

1. 2.3M
