Answer:
0.7802 M
Explanation:
Data:
- V (volume) = 100.0 mL → V = 0.1000 L
- m (mass) = 6.631 g → n = 0.07802 mol
Wanted:
- M (Molarity)
Equation:
M = [tex]\frac{mol}{L}[/tex]
Solution:
1. Convert mL to L:
- V = 100.0 mL x [tex]\frac{1 L}{1000 mL}[/tex] = 0.1000 L
2. Convert g to mol:
- n = [tex]\frac{6.631 g}{84.9947 g/mol}[/tex] = 0.07802 mol
3. Molarity Equation:
- M = [tex]\frac{0.07802 mol}{0.1000 L}[/tex] = 0.7802 M
Answer:
Explanation:
Mole weight of NaNO3 ====> ~~ 85 gm
6.631 / 85 = # moles in .1 liter
6.631/85 / (.1) = .78 M
