Hello i heed help. (Sorry if my English isnt correct)

-how many grams of salt we will have if we mix 0.5 moles Al₂O₃ with HNO₃. How many HNO₃ will be wasted

The amount of HNO₃ is not given. So not possible to calculate.

1. Develop the chemical equation, what is the product?
2. Read how much mole Al₂O₃ correspond to that product
3. How many mole of HNO₃ you need?
4. If amount of HNO₃ given then you can calculate the waste by difference.
