If we assume pure octane for gasoline first find a balance reaction then use the following setup for the calculations
50 kg x 1000g / 1kg x 114.232g / mol x Y mole CO2/Z mole octane x 44.01 g/mole CO2 = mass CO2
repeat process for water where Y moles is water and use molar mass for water at the last step and add masses together

What about conservation of mass where mass of products is 225 kg?

Thank you for pointing this out. I fell into a common mistake, use the mass of oxygen instead of octane and gange the first molar mass to 32 g/mol the rest of the calculation for CO2 is the same then do the same thing for H2O
