When $H_{2}S\left(g\right)$ is passed through an acidified solution of $K_{2}C{r}_2{O}_7$, the solution turns green with the formation of a precipitate. The weight of the precipitate formed when excess $H_{2}S$ is bubbled through 200 mL of 2 M acidified solution of $K_{2}C{r}_2{O}_7$ is ____g. [Atomic masses: H = 1, O = 16, S = 32, K = 39, Cr = 52]
