Question

The atmospheric pressure on a mountain is 550 mmHg and 1
atm is equal to 760 mmHg. What is the pressure in atm? Give
your answer to 2 significant figures.

Answer 1

Answer:

0.72

Explanation:

if 760=1

550=x

=550÷760= 0.72 in two s.f

Answer 2

The atmospheric pressure of the mountain will be 0.723 atm  

What is atmospheric pressure?

Air is everywhere around us at due to which it touches all the surfaces due to which they possess some pressure this exerted pressure is known as atmospheric pressure which can be calculated with this formula.  

1 atm = 760 mmHg

1 mmHg = 0.00131 atmosphere

Substituting the value of 1 atm in the given equation,

1mmHg = 0.00131 atmosphere

550 mmHg = 0.00131

= 550 × 0.00131

= 0.723 A T M  

It is the total force exerted by the atmosphere as AIR has small molecules and every molecule is possessing some weight as when they are in bulk they form layers these layers.

As we go above on the earth the atmospheric pressure will drops due to the increase in the altitude of the earth due to which there will be less amount of oxygen.

Therefore, the pressure will be 0.723 atm.
