Solution Steps

Step 1: Understanding the Relationship Between Mass and Molar Mass

The mass of 1.000 atm of gas increases as the molar mass of the gas increases. This is because, for a given volume and pressure, the mass of the gas is directly proportional to its molar mass.

Step 2: Calculating Moles of Propane

To find the number of moles of propane (\(\mathrm{C}_3\mathrm{H}_8\)) in the flask, use the formula: \[ \text{moles} = \frac{\text{mass}}{\text{molar mass}} \] For propane: \[ \text{moles of propane} = \frac{0.332 \, \text{g}}{44.097 \, \text{g/mol}} = 0.0075 \, \text{mol} \]

Step 3: Calculating Moles of Methane

For methane (\(\mathrm{CH}_4\)): \[ \text{moles of methane} = \frac{0.121 \, \text{g}}{16.043 \, \text{g/mol}} = 0.0075 \, \text{mol} \]

Step 4: Calculating Moles of Butane

For butane (\(\mathrm{C}_4\mathrm{H}_{10}\)): \[ \text{moles of butane} = \frac{0.438 \, \text{g}}{58.124 \, \text{g/mol}} = 0.0075 \, \text{mol} \]

Final Answer

\[ \boxed{\text{The mass of 1.000 atm of gas increases as the molar mass of the gas increases.}} \] \[ \boxed{\text{Moles of propane} = 0.0075 \, \text{mol}} \] \[ \boxed{\text{Moles of methane} = 0.0075 \, \text{mol}} \] \[ \boxed{\text{Moles of butane} = 0.0075 \, \text{mol}} \]

Problem 7: (11% of Assignment Value) A thin plastic rod of length d=2.4 m lies along the x-axis with its midpoint at the origin. The rod carries a uniform charge density of λ=8.5 nC / m. The point P is located along the y-axis at (0, y=25 cm). Part (a) Enter an expression for the electric potential at point P due to a small segment of the rod, of thickness d x, located at (x, 0). Give a symbolic answer in terms of λ, x, d x, y, and the Coulomb constant ke. d V= Part (b) Using the expression you entered in part (a), choose the correct limits for the integral that will give the electric potential at P. Part (c) Calculate the electric potential at P, in volts.
