Hello everyone, in this question they have asked that mole fraction of each component in a mixture.
00:06
So, here we are going to find out the mole fraction of each component in a mixture that contains 10 .7 grams of hydrogen, 66 .14 grams of nitrogen and 12 .26 grams of ammonia.
00:19
So, here first we are going to find out the number of moles of each component present in mixture.
00:24
So, first we are going to find out number of moles of hydrogen that is n of hydrogen is equal to mass of hydrogen that is they have given that is equal to 10 .7 grams upon molar mass of hydrogen is gram per mole.
00:38
So, here we get the number of moles of hydrogen is equal to 5 .35 moles.
00:45
After that we are going to find out number of moles of nitrogen which is equal to mass of nitrogen that is 66 .14 grams upon molar mass of nitrogen is 28 gram per mole.
01:01
So, here we get number of moles of nitrogen which is equal to 2 .36 moles.
01:07
Then we are going to find out the number of moles of ammonia.
01:12
So, mass of ammonia that is 12 .26 grams upon molar mass of ammonia is 17 gram per mole.
01:21
So, here we get the number of moles of ammonia which is equal to 0 .72 moles.
01:27
Then we are going to find out total moles here.
01:30
Total moles is equal to 5 .35 plus 2 .36 plus 0 .72...
