Using the information given for part A. Where else? To calculate the heat of combustion of benzo, a gas ID using the heat of combustion benzo gas and calculate the heat of combustion per mole of caffeine. So let's calculate the heat capacity of the calorie emitter First. The calorie emitter from the mass of Ben's OIC acid. This would be equal to 0.235 g of the Benzo a kassid over 1.642 degrees Celsius times 26.38 Killer jewels per 1 g of the Benz OIC acid on. We'll find that this is equal to 3775 Kill a Jules per degrees Celsius and then you can calculate the heat of combustion per mole of caffeine, Christian, Permal, caffeine and this would be quote, too. 1.525 degrees Celsius over 0.265 g of caffeine times 3.775 Kill a Jules per degrees Celsius times where Moeller mass here to convert to mold 190 Captain is a molar mass of 190 4.2 grounds in one more, and we find that the heat of combustion is equal to four point 22 times 10 to the third kilo joules per more for part B. Let's calculate the uncertainty in this measurement. They told that the uncertainty in the mouse eyes put 001 grams and our math of Ben Zoellick acid is 0.235 g. So this is equal to, um and we're gonna multiply this by 4220 kg jewels per mole. Okay. And this would be equal to 17 point 95 killer jewels because air uncertainty in that mouse. Second one, this 10.1 g over the mass of the caffeine, which is point 265 g times the combustion. And this was equal to 15 9 to killer jewels and the uncertainty in the temperatures 0.2 degrees Celsius over, uh, 1.642 degrees Celsius. Times feed a combustion, and this is equal to 5.146 kill jewels and second temperature measurement is one point 5 to 5 to be Celsius times for 2 to 0 kg joules per mole. But we find that this is equal to 5.53 killer jewels. So our uncertainty here be equal to 17.95 killer jewels plus 15 92 killer jewels plus 5.146 kill a Jules plus 5.53 Killah jewels. So our total uncertainty works out to, um, 44.55 killer jewels in our measurement, Yeah.
