The problem applies Charles' law since constant pressure with varying volume and temperature are given. Assuming ideal gas law, the equation to be used is =. We make sure the temperatures are expressed in Kelvin, hence the given added with 273. The volume 2 is equal to 25.2881 liters.
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
The formula to find the density of an object is mass/volume. You know the mass in this problem is 112.8 grams, and the volume is 63 cm^3. Now you can plug this information into the density formula as 112.8/63, which is about 1.8. Now you just add the cm^3/g and you have your answer.
