First, 55 g of Hg is 3.65 moles because one mole of Hg has a molar mass of 200.59
Then, the mole ratio of Hg to CaO is 8:4 or 2:1. SO we divide 3.65 by 2 to get 1.82 moles of CaO
This is the same as 102.06 grams because one mole of CaO has a molar mass of 56.0774
Hope this helps!
A. Molar Mass
Explanation:
Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass.
3) hydrogen and oxygen atoms forms water
