Identify the reaction order from each of the following rate : k=2.3 xx 10^5 L mol^(-1) s^(-1)

1.0L of solution which was in equilibrium with solid mixture of AgC1 and AgC1 and Ag_(2)CrO_(4) was found to contain 1xx 10^(-4) mol of Ag^(o+) ions, 1.0 xx 10^(-6) mol of C1^(Θ) ions and 8.0 xx 10^(-4) moles of CrO_(4)^(2-) ions. Ag^(o+) ions added slowely to the above mixture (keeping volume constant) till 8.0 xx 10^(-7) mol of AgC1 got precipitated. How many moles of Ag_(2)CrO_(4) were also precipitated?
