What is molar mass of carbon?
What is molar mass of carbon?
12.01g/mol
So a single carbon atom weighs 12 amu while a mole of carbon atoms weighs 12.01g/mol.
What is molar mass of c60?
720.66 g/mol
Buckminsterfullerene/Molar mass
What state of matter is 2nano3?
Sodium nitrate appears as a white crystalline solid. Noncombustible but accelerates the burning of combustible materials.
What is molecular mass of caco3?
100.0869 g/mol
Calcium carbonate/Molar mass
Why is a mole 6.022 x10 23?
The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×1023 elementary entities of the substance.

Why is the C60 form of carbon called buckminsterfullerene?
In this building in early September 1985, a team of scientists discovered a previously unknown pure carbon molecule, C60, which they dubbed buckminsterfullerene. The name was chosen because the geodesic domes of Buckminster Fuller provided a clue that the molecule’s atoms might be arranged in the form of a hollow cage.
How is carbon 60 made?
In the lab, C60 is made by blasting together pure carbon sources, such as graphite. In space, C60 was detected in planetary nebulae, which are the debris of dying stars. This environment has about 10,000 hydrogen molecules for every carbon molecule.
What is 2NaNO3?
Sodium nitrate (NaNO3) is a white solid at room temperature and is very soluble in water. Pure sodium nitrate is commonly used as a food preservative and rocket propellant. 2NaNO3 +CO2 + H2O.
How do you find the mass of CaCO3?
Find the molar mass of calcium carbonate by calculation.
- Chemical formula of calcium carbonate ⟶CaCO3.
- Mass of Calcium⟶40.
- Mass of Carbon⟶12.
- Mass of Oxygen⟶16.
- Multiply mass of each element by number of atoms of that element.
- Add all the masses obtained after multiplication.⟶CaCO3.
- =1×40+1×12+3×16. =40+12+48. =100.
