Question

if i have 2.4 moles of gas held at a temperature of 97 c and in a container with a volume of 45 L , what is the pressure of the gas

Answer 1

Answer:

1.62 L

Explanation:

T= 97+273.15= 370.15

R= 0.08206 atm/mol⋅K

V= 45 L

n= 2.4 mol

P= (n⋅R⋅T)/V

= (2.4 x 0.08206 x 370.15)/(45) = 1.61997 = 1.62

Answer 2

The pressure of the gas is 1.62 atm. This can be calculated by using ideal gas law that gives direct relation between P,V and T

Ideal gas Law:

This law states that pressure and volume are directly proportional to the temperature of the gas.

What information do we have?

T= 97+273.15= 370.15 K

R= 0.08206 atm/mol⋅K

V= 45 L

n= 2.4 mol

To find:

P=?

Ideal gas law is given by:

PV=n.R.T

P= (n⋅R⋅T)/V

P= (2.4 x 0.08206 x 370.15)/(45)

P= 1.61997

P= 1.62 atm

Thus, the pressure of the gas is 1.62 atm.
