Take 82 grams and divide it by the gfm of water which is 18 g/mole...(82g)/(18.0g/mole)=4.555 -> the answer is 4.6 moles
John Dalton in d year 1808 proposed d atomic theory..
1.All elements are made up of small, indivisble particles called atoms.
2.Atoms can neither be created nor destroyed.
3.Atoms of d same element are alike in every aspect, &differ from atoms of all other elements.
4. When atoms combine with other atoms, they do so in simple ratios.
Answer:
Hi the answer should be B or 2
Explanation:
Hope this helps!
Add up the molar mass of Mercury Oxide, and then divide the molar mass of Oxygen by the molar mass of the compound.
So...
mm of Hg + mm of O= 200.59g + 16g= 217g
16g/217g = .0737... x 100 = 7.37%
