divide by the Atomic Mass and times it by advogadro's number.
There are only THREE TYPES of atoms. They are carbon (C), hydrogen (H) and oxygen (O).
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
There are 3 Carbon atoms in C3H4. The numbers following the Element names (Like C, or H, or Na) is the amount of atoms in the compound. So there are 3 Carbon atoms and 4 Hydrogen atoms. That is incorrect the answer would be 4.53 x 1023 carbon molecules
5 moles carbon? 5 grams carbon? Both done. 5 moles carbon (6.022 X 1023/1 mole C) = 3.0 X 1024 atoms carbon =================== 5 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 2.5 X 1023 atoms carbon ==================== your choice
There are 3 carbon atoms in a molecule of C3, as indicated by the subscript "3" following the element symbol C.
1 mole C = 12.011g C = 6.022 x 1023 atoms C 0.020g C x (6.022 x 1023 atoms C)/12.011g C = 1.0 x 1021 atoms C
85.9 (g C) = 85.9 (g C) / 12.00 (g/mol C) = 7.158 (mol C)7.158 (mol C)*[6.022*1023 (atoms/mol C)] = 4.31*1024 C-atoms
There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
Three: 1 C and 2 O atoms
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
There are three carbon atoms and three oxygen atoms in each pyruvate molecule.
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
There is 1 carbon atom (C) and 1 oxygen atom (O) in a molecule of carbon monoxide (CO).
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
These are compound out of many Carbon and Hydrogen atom,In a single bonded and non cyclic carbon chain with as much as possible (= 'saturated with') single bonded H atoms to the C atoms.
One Carbon (C) atom and two Oxygen atoms (O). CO2.
