deflation - (geology) the erosion of soil as a consequence of sand and dust and loose rocks being removed by the wind; a constant deflation of the desert landscape. planation - the process of erosion whereby a level surface is produced. soil erosion - the washing away of soil by the flow of water.
The atomic mass of mercury is 200.59 grams per one mole (g/mol.) The molar mass of orange mercury(II) oxide is 216.59 grams per one mole (g/mol.) Sometimes you will see the atomic mass and molar mass of chemicals listed as their Molecular Weight or MW.
The mass of this condensed vapor is equal to the mass of vapor that fills the flask at the elevated temperature and barometric pressure. The molar mass of the liquid/vapor is then mass m = moles n M . We can compare the results of this procedure to the known molar mass of the compound. A result within 20% of the actual value is not unusual. Procedure 1.
