How many moles of copper ion are present in a 2.00*g mass of CuCl_2*2H_2O?

$\frac{2.00 \cdot g}{170.48 \cdot g \cdot m o {l}^{-} 1}$ $=$ ??mol
The give quotient is $\text{mass"/"molar mass}$, and the answer represents the number of moles of $C u C {l}_{2} \cdot 2 {H}_{2} O$, of aquated copper chloride.
