in a car engine a 250 mL cylinder and piston system is filled with a mixture of 0.42g and 0.24 g of octane gas and oxygen gas, respectively. Both gases are at room temperature of 33 c. If the total gas mixture is compressed to a pressure of 3.7 atm before combustion, calculate the total volume of gas mixture at this point in time.

Explanation:

Hello.

In this case, given the initial masses of both octane (C8H18, molar mass = 114 g/mol)) and oxygen (O2, molar mass = 32 g/mol), we can compute their moles and subsequently the total pressure via the ideal gas equation at 33 °C into the 250-mL:

After that, via the Boyle's law, we compute the final pressure in the cylinder and piston system:

Best regards!

the answer is na (sodium)
