octane is the primary ingredient in gasoline make the asssumption that all of the gas burned in the combustion of gas is octane
-the average highway mileage for cars is 27.5 mpg
-the average american drives 11,400 miles per year
-octanes density is 0.703g/mL
-assume the price of gas is $3.05 a gallon
-you drive 105 miles per month

what volume at STP of oxygen is consumed by the average driver over a year?

how much does it cost the average american to fill up their car for a year?

how much money would it cost to produce 102L of CO2 at STP?

what mass of CO2 do YOU generate during a month from burning gas?

what is the mass of gas YOU consume in that month?

Question 2:
in cellular respiration the chemical equation is C6H12O6 + 6O2 -----> 6CO2 + 6H2O +ATP energy

the average person breathes 500mL of air in each breath at STP
the air is 20.9% oxygen
you take 26 breaths per minute
you are 203 months old
the average life expectancy is 74 years old
one molecule of glucose provides 36 molecules of ATP
combustion of each mole of glucose releases 2830 kj of energy

what is the volume of oxygen at STP you have consumed in your life so far?

what is the mass of the CO2 produced by you in your lifetime so far?

if your only source of food is glucose what mass of glucose would you consume in one day?

what mass of glucose does the average person consume in their life?

Another question:
Saponification is the process by which soap is made. A triglyceride is reacted with NaOH to produce a carboxylic acid salt (the soap) and glycerol
Lard, mostly made of trioleic acid (TOA) is used with Lye (NaOH) in homemade variations
molar mass of TOA is 848g/mol
molar mass of resulting soap is 304g/mol
Relevant equations
TOA + 3NaOH --> 3 Soaps+ 3 glycerol

Question: if you want to make a 405g bar of soap with no excess lard or lye what amounts of lard and lye are needed?

if the lard costs $9.72/kg and the lye costs $53.65/kg what is the total production cost of the soap you made?

Please read forum rules.

Sorry, I did figure out the problem about the soap

For the cellular respiration problem I had to balance the equation myself so I have been working on these problems

The answer to the soap question is 377g Lard and 53.3g Lye and $6.52 for proof that I am worked on it
