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.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute (CuSO_4.5H_2O) = ?

V_s = volume of solution in ml

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

$0.10=\frac{n\times 1000}{100}$

$n=\frac{0.10\times 100}{1000}=0.01$

Therefore, the moles needed are 0.01.
