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
