how many moles of LiF would be required to produce a 2.5 M solution with a volume of 1.5 L?
To determine the number of moles of LiF required to produce a 2.5 M solution with a volume of 1.5 L, we can use the formula:
Molarity (M) = (moles of solute) / (volume of solution in liters)
Rearranging the formula, we have:
moles of solute = Molarity (M) * volume of solution in liters
Substituting the given values:
moles of solute = 2.5 M * 1.5 L
moles of solute = 3.75 moles
Therefore, you would need 3.75 moles of LiF to produce a 2.5 M solution with a volume of 1.5 L.
