if you started with 2.154g of aluminum, how many grams of aluminum oxide would you get?

Answer 1

1. Write and balance the equation.
4Al + 3O2 ==> 2Al2O3

2. Convert 2.154 g Al to moles. mole s= grams/molar mass

3. Using the coefficients in the balanced equation, convert moles Al to moles Al2O3.

4. Now convert moles Al2O3 to grams. g = moles x molar mass.

Answer 2

6.15x 10^27 moles Al2O3= g Al2O3
