Hello students here in this question we have given the mass of co2 that is 0 .974 gm.
00:06
From this we can estimate the mass of carbon.
00:16
So, we know that in 0 .974 gm the co2 molecular weight is 44 .0.
00:30
These two for co2 and we have to estimate the carbon.
00:34
So, the mass of carbon molecular weight that is 12 .01 for carbon.
00:41
So, we will get the mass that is 0 .2658168 gm for carbon.
00:53
Now we will estimate hydrogen from water.
01:08
So, the given mass of water that is 0 .1994 over the molecular weight of water that is 18 .01 and the molecular weight of water this is for water and for hydrogen it is 1 .007 gm for hydrogen.
01:34
So, we will get the mass of hydrogen that is 0 .0223126 gm hydrogen.
01:46
Now we have to calculate the mass of oxygen.
01:52
So, the total sample weight we have given that is 0 .5242 from here we can calculate the oxygen gm that would be equal to 0 .5242 is subtracted from the carbon that is 0 .2658168 that is the gm of carbon is also subtracted from the mass of hydrogen that is 0 .022316 gm of hydrogen.
02:28
We will get the oxygen mass gm that would be equal to 0 .23607066 gm.
02:43
So, now we will convert into mole...
