How many moles of MgCl2 are present in 5 liters of a 0.12 M MgCl2 solution?
mols = M x L = ?
.6 moles
To calculate the number of moles of MgCl2 present in a solution, you need to use the formula:
moles = molarity × volume
Given:
Molarity of MgCl2 solution = 0.12 M
Volume of the solution = 5 liters
Substitute the values into the formula to find the number of moles:
moles = 0.12 M × 5 L
moles = 0.6 moles
Therefore, there are 0.6 moles of MgCl2 present in 5 liters of a 0.12 M MgCl2 solution.
