Answer:
0.7802 M
Explanation:
<u>Data:</u>
- V (volume) = 100.0 mL → V = 0.1000 L
- m (mass) = 6.631 g → n = 0.07802 mol
<u>Wanted: </u>
<u>Equation: </u>
M = 
<u>Solution:</u>
1. Convert mL to L:
- V = 100.0 mL x
= 0.1000 L
2. Convert g to mol:
- n =
= 0.07802 mol
3. Molarity Equation:
- M =
= 0.7802 M
