Answer :
To calculate the number of moles in a solution, one can use the formula:
Moles = Molarity × Volume
Where:
- Molarity (M) is the concentration of the solution in moles per liter.
- Volume (L) is the volume of solution in liters.
In this case, the molarity is given as 2 M (moles per liter), and the volume of the solution is 5.6 liters.
Applying the values to the formula, we get:
Moles = Molarity × Volume
Moles = 2 M × 5.6 L
Moles = 11.2 moles
So, there are 11.2 moles in a 5.6 L solution of CaCl2 that is 2 M.
The correct answer is:
11.2 mol
