So in this given problem we have to balance the equation and write the coefficient.
00:08
So the given equation is h4 plus o2 gives co2 plus h2.
00:20
So the balance equation is equation is ch4 plus 2o2 gives co2 plus 2h2.
00:46
Number of moles is equal to is equals to mass over molar mass.
01:09
When we put the value, number of moles of ch4 is equals to 7 .60 multiply by 10 to the power minus 3 over molar mass of methane is 11 .019 gram per mole.
01:32
That is equals to 0 .00769 over 16 .01 gram per mole.
01:47
Number of moles of ch4 is equals to 0 .00047 moles.
02:00
If we can write this, the number of moles of ch4 is equals to 4 .74, multiply by 10 to the power minus 4 .4.
02:14
This is the number of moles of methane.
02:21
Now, 1 mole of ch4, now 1 mole of ch4 gives 1 mole of co2.
02:48
4 .74 multiplied by 10 to the power minus 4.
02:54
C .h4 gives 4 .74 multiplied by 10 to the power minus 4 over 1.
03:05
That is equal to 4 .74 multiply by 10 to the power minus 4 mole.
03:15
Now, mass of co2.
03:28
Mass of co2 is equals to 4 .74 multiplied by 10 to the power minus 4.
03:39
Multiply by 44 gram per mole...
