So this problem is just unit conversion.
00:06
Okay, so let us first calculate, convert the pressure in terms of pascal.
00:14
Okay, so for this, for a, we have the pressure in pascal.
00:20
This will be, sorry, let me write this.
00:24
It should be pascal, okay.
00:27
And we have 725 millimeters of mercury mmhg.
00:35
And how do we convert this to pascal? we're going to use atm because the conversion factor of pascal to atm is easier to memorize.
00:47
And atm to mmhg is also easier to memorize than mmhg to pascal directly.
00:56
So remember that 760 mmhg is equivalent to 1atm.
01:04
Okay, and then 1atm is equivalent to 100 ,1 ,325 pascal.
01:13
Okay, that's a conversion factor.
01:15
And that means you can cancel mmhg and atm, and our remaining unit in the numerator is pascal.
01:22
And that's our desired unit, right? and that means we have 96 .658.

0 .702...
