Answer:
- The molarity of the solution is 1.0 M
Step-by-step explanation:
1) Data:
a) n = 0.50 mol
b) V = 500 ml
c) M = ?
2) Formula:
- Molarity, M = number of moles of solute / volume of solution in liters
M = n / V (liter)
3) Conversion of units:
- 500 ml × 1.00 liter / 1,000 ml = 0.500 liter
4) Solution:
Substitute in the formula:
- M = n / V (liter) = 0.50 mol / 0.500 liter = 1.0 mol / liter = 1.0 M
The answer must be reported with two significant figures.
