One half of Avogadro's number, or about 3.011 X 1023.
four carbon atoms
There are 4 carbon atoms in butyne.

A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
Three atoms. Carbon dioxide is CO2
There are 5.0125 x 10^22 carbon atoms in 1 gram of carbon. 1 gram / 12.01 (GMW) x (6.02*10^23) (Avogadro's number) = 5.0125 x 10^22.
one gram of carbon* Avogdo's number =number of atom (many atom) one atom of carbon mean carbon have a 6 electron and 12 molar mass
In 12g of carbon-12, the molar mass of one carbon-12 atom is 12g/mol. This means that 12g of carbon-12 is equivalent to 1 mole of carbon-12 atoms. Avogadro's number states that 1 mole of atoms contains 6.022 x 10^23 atoms. Therefore, there are 6.022 x 10^23 atoms in exactly 12g of carbon-12.
Coal is an extremely complex mixture of carbon molecules and this number can not be defined exactly.
Unequivocally, exactly 1 gram in one gram.
four carbon atoms
If the compound stated in the question exists, its gram molecular mass is (14 times the gram atomic mass of carbon) plus (9 times the gram atomic mass of hydrogen) + (15 times the gram atomic mass of chlorine), or about 709 grams. Therefore, the number of molecules of the compound in 1.0 gram of it is (1.0)(Avogadro's number)/709 or about 8.49 X 1020. Each molecule contains 14 (exact) carbon atoms, for a total of 1.2 X 1022 atoms of carbon, to the justified number of significant digits.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
Avogadro's number, approximately 6 x 1023, tells us how many atoms molecules are in a mol. For example, it tells us approximately how many hydrogen atoms in a gram of hydrogen, how many carbon atoms in 12 grams, etc.
