What is the pressure in atmospheres for a gas that has a pressure of 655 Torr?
1 atmosphere pressure = 760 torr655 torr / ( 760 torr / ATM) = 0.86184 ATMIf you're not sure whether to multiply or divide when doing conversions, do this:655 torr . 1 ATM------------ * ---------1. . 760 torrThe formatting did not display exactly as I wanted it to appearThis is read like a fraction. Since 1 ATM = 760 torr, the numerator and denominator are equal, so it's like just multiplying by 1 and won't change the value.The torr units in numerator/denominator cancel out, and the only unit remaining is atmospheres.
