Answer:
one mole of HgO will give one mole of Hg.
Explanation:
Given data:
Moles of HgO = 1 mol
Moles of Hg = ?
Solution:
Chemical equation:
2HgO → 2Hg + O₂
Now we will compare the moles of Hg with HgO from balance chemical equation.
HgO : Hg
2 : 2
1 : 2/2×1 = 1 mol
So, one mole of HgO will give one mole of Hg.
7.22 moles of C2H6. Since there are 2 carbon atoms per C2H6, we must multiply the number of moles of C2H6 by 2 to get the number of moles of Carbon which is 14.4 or 14 if using two sig figs.
