3. A Pulaski High School senior was applying to college and wondered how many applications he needed to send. His counselor
explained that with the excellent grade he received in chemistry he would probably be accepted to one school out of every three
to which he applied. [3 applications = 1 acceptance] He immediately realized that for each application he would have to write 3
essays, (1 application = 3 essays) and each essay would require 2 hours work (1 essay = 2 hours). Of course writing
essays is no simple matter. For each hour of serious essay writing, he would need to expend 500 calories (1 hour = 500
calories) which he could derive from his mother's apple pies (1 pie = 1000 calories). How many times would he have to
clean his room in order to gain acceptance to 10 colleges? Hopefully you didn't skip problem No 1. I'll help you get
started 10 acceptances is the "given".

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap

A50.0 ml sample of gas at 20.0 atm of pressure is compressed to 40.0 atm of pressure at constant temperature. what is the new volume? 0.0100 ml 0.325 ml 25.0 ml 100. ml
