Problem 44P
To determine the mass of neon contained in a rigid, 2.0 L cylinder, you vary the cylinder’s temperature while recording the reading of a pressure gauge. Your data are as follows:
Temperature (°C) |
Pressure gauge (atm) |
100 |
6.52 |
150 |
7.80 |
200 |
8.83 |
250 |
9.59 |
Use the best-fit line of an appropriate graph to determine the mass of the neon.

ANSWER:
Step 1 of 3
We are going to find the mass of neon gas in a rigid cylinder. The pressure of the system is varied according to the temperature of the cylinder.
The volume of the cylinder \(\mathrm{V}=2 \mathrm{~L}=2 \times 10^{-3} \mathrm{~m}^{3}\)
The gas constant \(\mathrm{R}=8.314 \mathrm{~J} / \mathrm{mol} . \mathrm{K}\)
The molar mass of neon \(\mathrm{M}=20 \mathrm{~g} / \mathrm{mol}=20 \times 10^{-3} \mathrm{~kg} / \mathrm{mol}\)
