Question

7. HgO → Hg + O2

moles of oxygen?
0.5 moles of HgO decompose to produce how many moles of oxygen​

Answer 1

0.5 moles of HgO will produced 0.25 moles of oxygen

Step-by-step explanation:

Given data:

Number of moles of HgO = 0.5 mol

Number of moles of oxygen = ?

Solution:

Chemical equation;

2HgO → 2Hg + O₂

WE will compare the moles of HgO with oxygen from balance chemical equation.

HgO : O₂

2 : 1

0.5 : 1/2×0.5 =0.25 mol

So 0.5 moles of HgO will produced 0.25 moles of oxygen.
