How many moles of al2o3 will be formed when mixture of 5.4g of al and

1.	How many moles of al2o3 will be formed when mixture of 5.4g of al and 3.2g of oxygen is heated?
Answer» Moles of oxygen gas = 3.2/(162) = 0.1 moleSo, from the reaction we GET 4 moles of Aluminium REACTS with 3 moles of oxygen. From the equation we know that 0.2 mol of aluminum will react with: We get that 3/40.2 = 0.15 mol of the oxygen gas.

How many moles of al2o3 will be formed when mixture of 5.4g of al and 3.2g of oxygen is heated?

Answer»

Moles of oxygen gas = 3.2/(16*2) = 0.1 moleSo, from the reaction we GET 4 moles of Aluminium REACTS with 3 moles of oxygen. From the equation we know that 0.2 mol of aluminum will react with: We get that 3/4*0.2 = 0.15 mol of the oxygen gas.
