So to solve for this, we're going to calculate the amount of carbon from the amount of co2 and the mass of hydrogen from the amount of water.
00:14
So mass of carbon, if we have 27 .4 grams of co2, convert this to moles by dividing the molar mass of co2.
00:23
This is 44 .01, this is grams.
00:26
Then we have here moles.
00:28
And one mole of co2 will have one mole.
00:33
Of carbon right and then we multiply the um multiply the atomic mass of carbon that's 12 .01 is grams then we have here mole so that means we will get 7 .48 grams okay so mass of hydrogen we have 22 .46 grams of hydrogen h2o divided us by the molar mass of water it's 18 .02 grams then we have here moles and 1 mole of h2o will have 2 moles of h.
01:09
Right? multiply the atomic mass, 1 .01, 6 grams per mole of hydrogen.
01:16
And they'll get 2 .502 grams of hydrogen.
01:20
Now let's calculate the number of moles of each element here.
01:24
For carbon, we have 7 .408 grams.
01:28
Convert this to moles by dividing the whole atomic mass, 12 .01 grams.
01:33
We have moles...
