Answer:
=16.00 g/mole
Explanation:Oxygen’s atomic weight is 16.00 amu.
1 mole of oxygen is 6.02 x 1023 atoms of oxygen
1 amu = 1.661 x 10-24g
What is the molar mass (g/mole) of oxygen?
16.00 amu/oxygen atom x 1.661 x 10-24g/amu
= 2.657 x 10-24 g/atom x 6.02 x 1023 atoms/mole
=16.00 g/mole
Molar mass (in grams) is always equal to the atomic weight

I think the correct answer from the choices listed above is option C.
Calcium carbonate = CaCO3
sulfur dioxide = SO2
oxygen = O2
calcium sulfate = CaSO4
Carbon dioxide = CO2
The correct skeleton equation for the reaction would be CaCO3(s)+SO2(g)+O2(g) --> CaSO4(s)+ CO2(g).
Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or how much product will be formed in a reaction.
