They give us the balanced chemical reaction for butane.
00:04
That is two moles of butane, c4, h10, reacts with 13 moles of oxygen to produce 8 moles of carbon dioxide and 10 moles of water.
00:23
So if we have 1 gram of butane, we can convert that into moles butane using the molar mass butane, one mole.
00:36
C4h10 has a molar mass equal to four times the molar mass of carbon plus 10 times the molar mass of hydrogen, giving us 58 .12 grams.
00:53
Then from the moles of butane, we can calculate the moles of carbon dioxide.
01:00
We see from the balanced chemical reaction that two moles, produce 8 moles carbon dioxide, and we get 0 .0 688 moles carbon dioxide.
01:27
Then assuming it follows the ideal gas law, we can calculate the volume of carbon dioxide, setting its volume equal to its moles times the r constant times temperature in kelvin, divided by pressure...
