Question

What is the volume, in liters, occupied by 1.73 moles of N2 gas at 0.992 atm pressure and a temperature of 75º C?  (R value- 0.08206)​

Answer 1

48.70 is the volume, in liters, occupied by 1.73 moles of Nitrogen gas at 0.992 atm pressure and a temperature of 75º C.

Step-by-step explanation:

Data given:

number of moles of nitrogen gas = 1.73 moles

pressure of the gas = 0.992 atm

temperature of the gas = 75 degrees or 273.25 + 75 = 348.15 K

R (gas constant) = 0.08206 L atm/molesK

volume of the nitrogen gas under these conditions =?

The formula used is of ideal Gas Law:

PV = nRT

Rearranging the equation to get,

V =
`(nRT)/(P)`

putting the values in the equation:

V =
`(1.73 X 0.08026 X 348.15)/(0.992)`

= 48.70 Litres

the volume of the gas is 48.70 litres from the standard values used in the equation.
