When the volume and quantity of the gas are held constant, we can use the Gay-Lussac's Gas Law expressed as
P1/T1 = P2/T2
in which if the pressure of the gas decreases, we know that the temperature decreases.
We first convert the temperature to absolute temperature
T1 = 70 + 273 = 343 K
Rearranging the Gay-Lussac's equation to solve for the final temperature
T2 = P2T1 / P1
= (720 mmHg)(343 K) / 740 mmHg
= 334 K = 61ºC
Density = mass/volume
density = 81 grams/0.9 cubic centimetersdensity = 90 grams per cubic centimeter
The density of the sample is 90 grams per cubic centimeter.
