Please help me, determine the molarity of a solution containing 2.5 moles CuSO4 in 4.2 L of water
mols CuSO4 = grams/molar mass
M = mols CuSO4/L soln.

To determine the molarity of a solution, you need to know the number of moles of solute (in this case, CuSO4) and the volume of the solution (in this case, water).
The formula for molarity (M) is:
M = moles of solute / volume of solution in liters
In this case, you have 2.5 moles of CuSO4 and a volume of 4.2 L of water.
Plugging these values into the formula, we get:
M = 2.5 moles / 4.2 L
Now calculate this to find the molarity.
