Answer:

94.4mg is the answer.

Explanation:

mass of gold = 0.175g = 175mg

no. of moles = given mass / relative atomic mass

n = 175/197

n = 0.888 mol.

From the equation, mole ratio of Gold to Chlorine is 2:3

moles of chlorine = 1.5 × 0.888 = 1.33

no. of moles (chlorine) = mass/(35.5 × 2)

1.33 = m/71

m = 94.4mg

∴ mass of chlorine = 94.4mg
