🤓 Based on our data, we think this question is relevant for Professor Roychowdhury's class at RUTGERS.
MgO(s) + CO2(g) → MgCO3(s)
Moles CO2 reacted = moles CO2 initially - moles CO2 excess
The oxides of Group 2A metals (symbolized by M here) react with carbon dioxide according to the following reaction:
MO(s) + CO2(g) → MCO3(s)
A 2.85-g sample containing only MgO and CuO is placed in a 3.00-L container. The container is filled with CO2 to a pressure of 740. torr at 20.°C. After the reaction has gone to completion, the pressure inside the flask is 390. torr at 20.°C. What is the mass percent of MgO in the mixture? Assume that only the MgO reacts with CO2.
