Molarity and Dilution How many moles are needed in a 100. mL solution of a 0.10M CuSO4 5H2O solution?

The moles needed are 0.01.

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute = ?  

= volume of solution in ml  

Now put all the given values in the formula of molarity, we get

Therefore, the moles needed are 0.01.
