Carry out the following conversions: (b) 0.255 atm to mm Hg

Video transcript

Welcome back everyone. We need to convert 0.2 31 A t M's two millimeters of mercury. Let's recall that units of a T. M's and millimeters of mercury are both units of pressure. And we also should recall that pressure is a continuous physical force exerted on or against an object. Buy something in contact with it so with the object. So to begin our conversion, we're just going to start with the .231 ATM. And we should recall that we can actually directly convert from a T. M's two millimeters of mercury by using a conversion factor. Where we would recall that 1 80 M is equivalent to 760 millimeters of mercury so we can cancel out a. T. M. S. Leaving us with millimeters of mercury as our final unit of pressure. And when we multiply in our calculators were going to yield a result of 175.56 millimeters of mercury. And going back to the prompt were given three sig figs for our pressure. So we're gonna round this to about three sig figs as 176 millimeters of mercury. And this would be our final answer. When we convert 1760.2 31 A T. M. S. To 176 millimeters of mercury. I hope everything I reviewed was clear. If you have any questions, please leave them down below and I'll see everyone in the next practice video
