Answer:
0.231 mol
Explanation:
Given data:
Moles of oxygen produced= ?
Mass of mercury(II) oxide = 100 g
Solution:
Chemical equation:
2HgO → 2Hg + O₂
Number of moles of mercury oxide:
Number of moles = mass/ molar mass
Number of moles = 100 g/ 216.6 g/mol
Number of moles = 0.462 mol
Now we will compare the moles of oxygen with mercury oxide.
HgO : O₂
2 : 1
0.462 : 1/2× 0.462 = 0.231 mol
