1) If you have a 10.0 L tank of acetylene at 25.0 C and 1.00 atm pressure, how many moles of CO2 will be produced if you burn all the acetylene in the tank. 2C2H2 (g) + 5O2(g) -- 2H20(g) +4CO2 2) a. What is the volume of one breath on Mt Everest it temp is -60C and Pressure is 253mm Hg (Human breathes .5 L per breath assume conditions are STP) b. Air has 21% oxygen if O2 is 14% on everest what volume of air does one need to breath to get same amount of O2? 3) What is the density (in g/L) of C2H2F4 at STP Find the molecules per liter of C2H2F4 at 220C and 1.0 atm

joannablackwelder · Answer

At STP (25 C, 1 atm) 1 mol of ideal gas = 22.4 L

joannablackwelder · Answer

So, from 10 L you can calculate the number of moles of acetylene and from the mole ratio calculate the number of moles of CO2.
