According to the EPA... If someone burns fossil fuels<span>, the reaction releases nitrogen oxides up and into the atmosphere. This </span>contributes<span> to the creation of smog (sometimes acid rain). The biggest sources of nitrogen oxide emissions are: vehicles, coal power plants, ships, airplanes, and large industrial operations.</span>
Answer:
0.690 g/mL
Explanation:
Density is the ratio of mass to volume:
gasoline mass = (flask+gas mass) - (flask mass) = 145.028 g -110.525 g
gasoline mass = 34.503 g
Density = (gas mass)/(gas volume) = (34.503 g)/(50.0 mL)
Density = 0.690 g/mL
_____
The least-precise number in this calculation is the sample volume, which has 3 significant figures. Thus, the answer is good only to 3 significant figures.

Answser: a curved line.
Justification:
Boyle's law states that a constant temperature the volume of a certain amount of gas is inversely related to the pressure:<em> pV = k.</em>
The graph of two inverseley related variables is a curve: as one variable increases the other decresases.
In such a curve for any pair of points it is obeyed Boyle's law: pV = constant, so:
<em> p₁V₁ = p₂V₂ = p₃V₃ = ... = k</em>
Mathematically, the graph represents a hyperbola: as the value of one of the variables increase the other trends to zero, so the curve approaches the axis without touching them.
See the figure attached to visualize the form of the curve.
