An automobile travels 225 miles at 20.5 miles/gallon. What is the amount of carbon dioxide produced if the gasoline is composed of octane (C8H18) whose density is 0.69 g/mL.
S7P6A66 (grouping/interaction- chemical)
Both Pj Problem are of Interest, however, Pj Problem of type grouping/interactio (chemical) is in focus.
Combustion of octane as follows:
2C8H18 + 25O2 -------> 16CO2 + 18H2O
Total gallons of octane combusted = 225/20.5 = 10.98 gallons = 10.98 x 3.79 liters = 41.54 Liters
density per liter = 0.69/0.001 = 690 g/L
So, mass of octane = density x volume = 690 x 41.6 = 28704 g
Molar mass of octane = 12x8 + 1x18 = 96 + 18 = 114 g
So, moles of octane combusted = 28704/114 = 251.8 moles
From balanced equation:
2 moles of C8H18 produced 16 moles of CO2
So, 251.8 moles of C8H18 produce (251.8 x 16)/2 = 2014 moles of CO2
Molar mass of CO2 = 12 + 32 = 44 g
So, mass of 2014 moles = 44 x 2014 = 88616 g = 88.6 kg.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
