That is about the mole definition of Avogadro's number, so.
6.022 X 10^23 atoms of carbon
1.2 grams carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C)
= 6.02 X 10^22 atoms of carbon
four carbon atoms
Amount of Mg = 12/24.3 = 0.494mol 1 mol of Mg contains 6.02 x 1023 Mg atoms (avogadro constant). Number of atoms in 12g of Mg = 0.494 x 6.02 x 1023 = 2.97 x 1023
Decane has 10 carbon atoms and 22 hydrogen atoms.
Nonane has 9 carbon atoms and the formula of C9H20
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
1
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.

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
Amount of Mg = 12/24.3 = 0.494mol 1 mol of Mg contains 6.02 x 1023 Mg atoms (avogadro constant). Number of atoms in 12g of Mg = 0.494 x 6.02 x 1023 = 2.97 x 1023
There are 4 carbon atoms in butyne.
Hydrogen was used as the base since it has an atomic number of 1, it took 6.02 x 10^23 hydrogen atoms to make 1 gram of hydrogen.
carbon can bond with 4 different atoms.
The answer is 6,2729.10e+26 carbon atoms.
