Question

500ml h2 gas at 4atm and 300ml o2 gas at 10atm they were mixed in 2l vessel . Then find partial pressure of both gas and total pressure

Answer 1

Answer:

what.......,.......,....,....,?

Answer 2

Answer:

The answer to the given question is the partial pressure of hydrogen gas is 1 atm and oxygen gas is 1.5 atm.

Therefore, the total pressure on the final vessel is 2.5 atm.

Explanation:

Given :

500ml of hydrogen gas at 4atm and 300ml of oxygen gas at 10atm

They are mixed in a 2-litre vessel.

To find :

the partial pressure of both gas and total pressure.

Solution :

Partial pressure is defined as the pressure of the individual gas when it is placed in a required vessel or a final vessel.

On changing the litre to a millilitre

1 litre is equal to 1000 milli litre.

Therefore, the volume of the final vessel is 2000 ml.

Initially, the volume of hydrogen gas is 500 ml at 4 atm.

after placing it in a vessel of volume 2000 ml is

P1V1=P2V2

on substituting the values, we get the answer as

$500 \times 4 = 2000 \times x$

the value on the right divides the value on the left

$\frac{2000}{2000} = x \\ x = 1$

The partial pressure of hydrogen gas at a 2-litre vessel is 1 atm.

Now, 300ml of oxygen gas at 10atm was placed in a 2-litre vessel.

Then the partial pressure of oxygen gas is

P1V1= P2V2

$300 \times 10 = 2000 \times y$

The value on the right divides the value on the left.

$\frac{300 \times 10}{2000} = y \\ \frac{3000}{2000} = y$

on dividing, we get the value as 1.5 atm.

The partial pressure of hydrogen gas is 1 atm and oxygen gas is 1.5 atm.

Therefore, the total pressure on the final vessel is 2.5 atm.
