0.2 moles of carbon dioxide. If the temperature of the
mixture is 300 K, then the pressure of it will be nearly​

Answer 1

Answer:

A vessel of volume

contains

of oxygen and

of carbon dioxide. If the temperature if the mixture is

, find its pressure.

Answer 2

Given:

A vessel of volume 2 litre contains 0.1 moles of oxygen and 0.2 moles of carbon dioxide. If the temperature of the mixture is 300 K.

To find:

Pressure in the container ?

Calculation:

Let us consider that both oxygen and carbon dioxide are ideal gases such that:

$\therefore \: PV = nRT$

• P is pressure
• V is volume
• n is total moles
• R is universal gas constant
• T is temperature

$\implies P= \dfrac{nRT}{V}$

$\implies P= \dfrac{(0.1 + 0.2) \times 8.314 \times 300}{2}$

$\implies P= \dfrac{(0.3) \times 8.314 \times 300}{2}$

$\implies P= \dfrac{748.26}{2}$

$\implies P= 374.13 \: Pa$

So, pressure is 374.13 Pascal.
