What is the volume of a gas balloon filled with 4.0 moles of tha gas, when the barometer reads pressure of 780 Torr and temperature is 30°C.​

Answer :

Neetoo

Answer:

V = 96.61 L

Explanation:

Given data:

Number of moles = 4.0 mol

Pressure = 780 torr (780/760 = 1.03 atm)

Temperature = 30°C

Volume of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

1.03 atm × V = 4.0 mol × 0.0821 atm.L/ mol.K  × 303 K

V = 99.505 atm.L / 1.03 atm

V = 96.61 L
