Mercury unit of measure

Web26 nov. 2024 · Atomic mass of Mercury is 200.59 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. WebThe millimeter of mercury by definition is 133.322 387 415 Pa ( 13.5951 g/cm3 × 9.806 65 m/s2 × 1 mm ), which is approximated with known accuracies of density of mercury and gravitational acceleration. The torr is defined as 1∕760 of one atmosphere, while the atmosphere is defined as 101.325 kPa.
