Hi there, in this question we have given 2 .50 moles of potassium per magnet, 45 .9 moles of carbon dioxide and 1 .25 multiply by 10 raised to power minus 2 moles of blue vitriol.
00:20
Okay, copper sulfate .5h2o.
00:23
Here we have to find out moles of oxygen and oxygen.
00:33
Atoms present.
00:35
Now let's start solving our question.
00:38
First we have 2 .50 mole of potassium per magnet.
00:48
As we can see here is 4 atoms of oxygen.
00:54
So 1 mole of kmno4 contain 4 more of oxygen atom.
01:13
Okay, so 2 .50 mole of kmno4 contain 4 multiplied by 2 .50 moles of oxygen atom.
01:39
So the answer is 10 moles of oxygen atom.
01:44
Of oxygen atom.
01:49
Okay, 2 .50 mole of kmno4 contain 10 moles of oxygen atom.
02:08
So this is the answer of the first part.
02:13
Now let's move to the second part of this question.
02:17
B, here we have 45 .5.
02:21
0 .9 mole of carbon dioxide.
02:27
Okay, so in carbon dioxide we can see we have two atoms here.
02:32
So how much atom we have in one mole? 1 mole of co2 contain 2 mules of oxygen atom...
