The atomic mass would not change since the mass of an electron is negligible compared to the mass of protons and neutrons
A mole of CO2 = 2 moles of O2
8 CO moles x 2 =
16 moles
The mass of the product is <em>98.78 g.</em>
The word equation is
aluminum + chlorine → product
20.00 g + 98.78 g → <em>x</em> g
If each reactant is completely consumed, the <em>Law of conservation of Mass </em>tells us the mass of the product must be 98.78 g.
