130.2 g

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Cl_2=\frac{78.9g}{71g/mol}=1.11moles$

$2GaCl_3+3F_2\rightarrow 2GaF_3+3Cl_2$

According to stoichiometry :

3 moles of Cl_2 require = 2 moles of GaCl_3

Thus 1.11 moles of Cl_2 will require= $\frac{2}{3}\times 1.11=0.74moles$ of GaCl_3

Mass of $GaCl_3=moles\times {\text {Molar mass}}=0.74moles\times 176g/mol=130.2g$

Thus 130.2 g of gallium chloride would react with excess fluorine to produce 78.9 g of chlorine
