You are explaining the rules of nomenclature to a friend. You state the name of the compound NF3 as nitrogen trifluoride. Your friend says, 'Oh, so AlF3 must be aluminum trifluoride' Is your friend correct? Explain.

Answer is 1 atm = 760 mm Hg.

There are many units which are used to measure the pressure. Examples are atm, Pascal (Pa), torr, mm Hg and bar.
Although there are many units, the SI unit is Pascal (Pa). The relationship between those units as follows;

1 atm = 101325 Pa = 1.01325 bar = 760 mm Hg = 760 torr.
