1 mol of He contains apx 6.02214x10^23 atoms
The answer is 8,1547.10e25.
How many hydrocarbon with only carbon-carbon single bond and n number of Carbon atoms how many hydrogen atoms are there in terms of nv
20 It is 4!
The answer is 6,2729.10e+26 carbon atoms.
3
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
On which planet?
1 mol of He contains apx 6.02214x10^23 atoms
Elements with atomic numbers 1-5 are lighter than carbon.
The number of helium atoms is 6,022 140 857.10e26.
Carbon atoms can be bonded together.

Helium does not form molecules but exists as individual atoms.
100 million helium atoms, being the number (1.0E-2 m)/(100E-12 m).
Helium has one kind of atom: helium.
The answer is 8,1547.10e25.
