Step 1

Given information:

Mass of sample = 1.95 g

Temperature = 61 °C

Pressure of gas = 1.00 atm

Volume of flask = 1.45 L

Step 2

Ideal gas law gives the empirical relationship between pressure, volume, temperature, and amount of gas that is number of moles of a gas. The ideal gas equation is represented as follows: help_outlineImage TranscriptionclosepV nRT where,Pispressure of the gas Visvolumeoccupied by the gas nisnumber of moles of the gas Risproportionality constant(Universalgas constant having a value 0.082 1L. atm/mol.K) Tis thetemperature fullscreen
Step 3

As, the temperature of gas is given in degree Celsius so,...
