Question

What volume will 1.14 moles of CO2 gas occupy at STP?​

Answer 1

As we know STP means Standard Temperature and Pressure. Where, Pressure is 1 atm and temperature is 273 K and also Ideal gas law ( PV=nRT)

Where –

• P = Pressure in atm
• V = Volume in L
• n = moles
• R = Ideal gas law constant
• T = Temperature in K

Now, according to the question –

• n = 1.14 moles
• P = 1 atm
• T = 273 K
• R = 0.0821 atm L/ mol K

Calculation –

$\qquad$ $\pink{\twoheadrightarrow\bf PV = nRT}$

$\qquad$ $\twoheadrightarrow\sf V = \dfrac{nRT}{P}$

$\qquad$ $\twoheadrightarrow\sf V =\dfrac{ 1.14 \times 0.0821 \times 273 }{ 1}$

$\qquad$ $\twoheadrightarrow\sf V = \dfrac{25.55}{1}$

$\qquad$ $\pink{\twoheadrightarrow\sf V = 25.55 L}$

• Henceforth, Volume is 25.55 L.
