find the moles of Al ... (sample mass) / (molar mass)
find moles of O reacted ... three moles of O for every two moles of Al
... (3/2) * (moles Al) = (moles O)
find mass of O reacted ... (moles O) * (molar mass O)
add the mass of O to the mass of Al
find moles of O reacted ... three moles of O for every two moles of Al
... (3/2) * (moles Al) = (moles O)
find mass of O reacted ... (moles O) * (molar mass O)
add the mass of O to the mass of Al
