Is molecular mass and molar mass are same?
It can also be expressed as kilogram per mole. Molecular mass is expressed in atomic mass units….Molar mass:
| Difference between Molar mass and Molecular mass | |
|---|---|
| Example: Mass of 1 mole of oxygen is 15.9994 grams. Therefore, the molar mass = 15.9994 g/mol | Example: Molecular mass of Ca(OH)2 = 74 atomic mass units |
How do you calculate molar mass from atomic mass?
Molar mass = mass/mole = g/mol This leads to two important facts. The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. The mass of one mole of carbon-12 atoms is exactly 12 grams; its molar mass is exactly 12 grams per mole.

What is the boiling point of silicon tetrafluoride?
Silicon tetrafluoride. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Silicon tetrafluoride or tetrafluorosilane is the chemical compound with the formula SiF4. This colorless compound is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
Is silicon tetrafluoride toxic to humans?
Silicon tetrafluoride appears as a colorless, nonflammable, corrosive and toxic gas with a pungent odor similar to that of hydrochloric acid. Very toxic by inhalation. Vapor is heavier than air. Under prolonged exposure to heat the containers may rupture violently and rocket.
What happens when silicon tetrafluoride is hydrolysed?
The silicon tetrafluoride is partly hydrolysed and forms hexafluorosilicic acid . ^ a b Silicon Compounds, Silicon Halides.
How is silicon tetrafluoride produced in volcanoes?
Volcanic plumes contain significant amounts of silicon tetrafluoride. Production can reach several tonnes per day. Some amounts are also emitted from spontaneous coal fires. The silicon tetrafluoride is partly hydrolysed and forms hexafluorosilicic acid .
