Chromium metal can be plated out from an acidic solution containing `CrO_(3)` according to the following equation.
`CrO_(3)(aq)+6H^(+)(aq)+6e^(-)rarrCr(s)+3H_(2)O`
Calculate (i) How many grams of chromium will be plated out by 24,000 C and (ii) How long will it take to plate out 1.5g of chromium by using 12.5 current?

Text Solution
