So to solve for this, the pressure of the gas will be equivalent to the pressure of the gauge pressure and then we add the atmospheric pressure.
00:21
Okay, so that means based on the gauge, the pressure for this is density of the density of mercury.
00:32
Multiplied by gravity g and then h will be the height of b the height of mercury in the monometer then we add the we add the atmospheric pressure which is given as 756 .0 mhmhc so that's right here 756 .6 .m .hcg let's substitute the values.
01:03
We have a density of mercury is 13 ,600 kilograms per cubic meter.
01:14
And then gravity is 9 .8 meters per second squared.
01:21
And then we have the height which is 8 .40 centimeters.
01:25
So let's convert this to meters.
01:27
100 centimeters, we've lengthed to one meter.
01:30
So that means we could cancel some units.
01:34
We'll cancel seven meters and then meters, meters, meters.
01:38
So that means we only have one meter in the denominator now.
01:44
So our answer for this will also add the 700.
01:52
So sorry, that's right of conversion factor also...
