Question

A closed container is filled with oxygen. the pressure in the container is 435 kpa . what is the pressure in millimeters of mercury?

Answer 1

57 millimeter, I think

Answer 2

First of all, let's convert the pressure in Pascal:

`p=435 kPa=435 000 Pa`

Keeping in mind that
`1 atm = 101 300 Pa`, we can convert it into atmospheres:

`1 atm : 101 300 Pa = p :435 000 Pa`

`p=(435 000 Pa \cdot 1 atm)/(101 300 Pa)=4.3 atm`

We know that 1 atm corresponds to 760 millimeters of mercury, so we have:

`1 atm = 760 mmHg = 4.3 atm : p`

From which we find the pressure in millimeters of mercury:

`p=(760 mmHg \cdot 4.3 atm)/(1 atm)=3268 mmHg`
