🤓 Based on our data, we think this question is relevant for Professor Williams' class at ASU.
We are being asked to determine the amount of GaAs after the reaction of 600 g trimethylgallium with 400 g of arsine.
To solve this problem, we use the concept of limiting reactant or reagent.
The limiting reactant or limiting reagent is the compound that determines the maximum amount of product obtained in a chemical reaction.
The semiconductor gallium arsenide, GaAs, is used in highspeed integrated circuits, light-emitting diodes, and solar cells. Its density is 5.32 g/cm3. It can be made by reacting trimethylgallium, Ga(CH3)3, with arsine gas, AsH3. The other product of the reaction is methane, CH4.
If you reacted 600 g of trimethylgallium with 400 g of arsine, what mass of GaAs could you make?
