Question

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 300 g of trimethylgallium with 200 g of arsine, what mass of GaAs could you make?
