Molarity and Dilution
Aleonysh [2.5K]

Answer: 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.
