Answer:
Explanation:
1) Data:
a) Molarity, M = ?
b) Number of moles, n = 0.400 mol
c) Volume, V = 9.79 liters
2) Formula:
The definition of molarity is number of moles of solute per volume of solution in liters.
3) Calculations:
- M = 0.400 mol / 9.79 liter = 0.04086 M
You must use three significant digits to report the answer correctly, so it is M = 0.0409 M.
