Please help me. Finding mass.
« on: September 25, 2019, 11:21:13 AM »
In a reaction between copper metal and aqueous iron (III) chloride, Fe 3+ is reduced to Fe2+ while Cu is oxidized to Cu 2+. What is the mass of Cu required to react with 50 mL of 1 mol/L FeCl3?

The answer is 1.6 grams. It would be really helpful if you tell me the solution. Thank you.

Write down a balanced reaction, calculate number of moles FeCl3 and do stoichiometric calculations.

The answer is for the atomic mass of copper 64.

Hello! Can you please give a step-by-step solution? I'm still a baby in chemistry and can't comprehend things that much. It would be very helpful! Thank you! :D
