Assuming gasoline is 89.0% isooctane, with a density of 0.692 g/mL, what is the theoretical yield (in grams) of CO2 produced by the combustion of 1.62 x 1010 gallons of gasoline (the estimated annual consumption of gasoline in the U. S.)

1.164 × 10¹⁴ g

Explanation:

1.62 × 10¹⁰ gallons = 1.62 × 10¹⁰  × 3.785 litres = 6.1317 × 10¹⁰ L

mass = density × volume = 6.1317 × 10¹⁰ × 1000 ml × 0.692 g/ml = 4.24 × 10¹³ g

4.24 × 10¹³ g × 0.89 = 3.776 × 10¹³ g

2 C₈H₁₈ + 25 O₂ → 16 CO₂ + 18 H₂O

molar mass of isooctane = 114. 22 × 2 moles = 228.44 g

molar mass of CO₂ = 44.01 × 16 moles = 704.16 g

228.44 yields  704.16 g

3.776 × 10¹³ g will yield   (3.776 × 10¹³ g × 704.16 g) / 228.44 = 1.164 × 10¹⁴ g

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
