Answer:
[tex]312 \ mol \ solute[/tex]
General Formulas and Concepts:
Chemistry
- Molarity = moles of solute / liters of solution
Explanation:
Step 1: Define variables
M = 0.722
L = 431.9
m = x
Step 2: Solve for x
- Substitute: [tex]0.722 \ M=\frac{x \ mol}{431.9 \ L}[/tex]
- Isolate x: [tex]311.832=x \ mol[/tex]
- Rewrite: [tex]x=311.832 \ mol[/tex]
Step 3: Check
Our smallest sig figs is 3. Follow sig figs rules.
[tex]311.832 \ mol \approx 312 \ mol \ solute[/tex]
