If a gas at 25.0 degrees Celsius occupies 7.20 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 a
Finger [1]

Answer:

2.88 L.

Explanation:

  • To calculate the no. of moles of a gas, we can use the general law of ideal gas: <em>PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant.

T is the temperature of the gas in K.

  • If n and T is constant, and have two different values of (P and V):

<em>P₁V₁ = P₂V₂</em>

<em></em>

P₁ = 1.0 atm, V₁ = 7.2 L.

P₂ = 2.5 atm, V₂ = ??? L.

<em>∴ V₂ = P₁V₁/P₂ </em>= (1.0 atm)(7.2 L)/(2.5 atm) = <em>2.88 L.</em>
