Hello students let's discuss the question so in this question we have a sample of h2 s .s .o.
00:06
4 and from that sample we need to discover the mass of sulfur and also the mass of oxygen present in that h2 s .o4 sample so let's start here we all know total mass of the sample total mass of first sample we have two samples so the total mass of first sample will be equal to 2 .02 plus 32 .07 plus 64 this is for hydrogen this is for oxygen and this is for sulfur so this will be equal to 98 .04 grams now we have to calculate the percentage of hydrogen sulfur and oxygen present so here we can say percentage of hydrogen sulfur and oxygen present so here we can say percentage of hydrogen sulfur and oxygen is what we need to find over here so here let's find it one by one so percentage of hydrogen will be equal to mass of hydrogen upon total mass so here we can say mass of hydrogen divided by the total mass of hydrogen so here we can say this is equal to multiplied by hundred so this is equal to 2 .02 divided by 98 .04 grams multiplied by 100.
01:41
So this will be equal to 2 .06 percentage.
01:48
So this is the mass of hydrogen over your percentage of hydrogen.
01:53
So now let's see the percentage of sulfur present.
01:58
This will be equal to mass of sulfur.
02:03
Sulfur divided by total mass of sulfur multiplied by 100.
02:13
So this will be equal to 32 .07 divided by 98 .04 grams multiplied by 100 and this will be equal to 32 .71 percentage.
02:30
This is the percentage of sulfur present.
02:33
Now let's see the percentage of oxygen.
02:34
So here we can say percentage of oxygen will be equal to mass of oxygen divided by the total mass of oxygen multiplied by 100.
02:51
And this will be equal to 64 grams divided by 98 .04 grams multiplied by 100.
02:59
Multiplied by 100 and this will be equal to 65 .27 percentage.
03:06
This is the percentage of oxygen.
03:09
Now we need to calculate the total mass of second sample.
03:12
This was the total mass of first sample...
