Question

part 1 of 3
calculate the molarity of each aqueous solution with the given amount of $\text{mgcl}_2$ and final volume. be sure each of your answer entries has the correct number of significant figures.
note: reference the si prefixes table for additional information.
1.10 mol $\text{mgcl}_2$ in 0.720 l solution

Explanation:

Step1: Recall molarity formula

Molarity $M = \frac{\text{moles of solute}}{\text{volume of solution (L)}}$

Step2: Substitute given values

$M = \frac{1.10\ \text{mol}}{0.720\ \text{L}}$

Step3: Calculate and round sig figs

$M = 1.5277... \approx 1.53$ (3 significant figures, matching the least number of sig figs in given values)

Answer:

1.53 M
