Hi! I am unsure of how to solve this problem. Thank you!
||| Understanding Boyle's Law A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 166. kPa. The piston is now pulled up, expanding the gas, until the gas has a final volume of 87.0 L. Calculate the final pressure of the gas.

Gaseous mixture: 0.943 g air (0.006846 mol O2 and 0.025754 mol N2) 0.0641 g gas (5.05 x 10^-4 mol isooctane and 1.39 x 10^-4 mol ethanol) In “the intake stroke”, the air/C8H18 gaseous mixture in Question 3 is transferred into the cylinder, where the piston reaches the bottom of the cylinder. Assume the gas mixture an ideal gas behavior, the temperature of cylinder is 212 oF, and the total pressure of gas mixture is 1.00 atm, Calculate moles of C8H18, O2 and the total moles of air/fuel mixture?
$ IDI 4 R F V View Available Hint(s) 11.9 L Submit ✓ Correct A 142-kilometer trip is approximately 90 miles so it would make sense that it would take about 8-16 liters (or 2-4 gallons) of gas to make that trip, depending on the efficiency of your car. Part B While in Europe, if you drive 125 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 42.0 mi/gal? Assume that 1 euro = 1.26 dollars. Express your answer numerically in dollars.

Acetylene torches are used for welding. These torches use a mixture of acetylene gas, C2 H2, and oxygen gas, O2 to produce the following combustion reaction: 2C2 H2 (g) + 502 (9)→4CO2 (g)+ 2H2O(g) You have a 7.00 L gas tank and a 2.50 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 145 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time?
Sodium azide (NaN3) is used to inflate air bags in automobiles according to the following equation: ____ NaN3(s) ⟶ _____ Na(s) + _____ N2 (g) On your scratch paper, balance the equation. What mass of NaN3 (in grams) is needed to generate 20.5 liters of N2 measured at 720 mm Hg and 25oC? NaN3 = 65.01 g/mol N2 = 28.0 g/mol
72 g of CaCO3 is treated with 0.500 L of a 1.00M solution of HCl. What volume of CO2 gas, measured at 25˚C and 795. mm Hg can be obtained? (9 marks) CaCO3(s) + 2HCl(aq) → CO2(g) + CaCl2(aq) + H2O(l) Show all equation and all calculations involved to get full marks. Hint: this is a limiting type question! Use the following questions as a guide and include them in your answer. i. the limiting reactant is? ii. the maximum number of moles of CO2 gas that can be produced is? iii. the volume of CO2 gas that can be produced from this reaction is?
