According to Avagadro's number one mole of any substance is equal to 6.022*10^23 particles.
Knowing this you can calculate the number of atoms in 4.25 moles of carbon tetrabromide easily:
4.25(moles of carbon tetrabromide) * 6.022*10^23(atoms) = 2.559*10^24
So 2.559*10^24 atoms are present in 4.25 moles of carbon tetrabromide.
Carbon tetrabromide is the chemical name for the molecular formula CBr4. The weight of this molecular compound is 331.6 grams per mole. This is also its mass for one mole.
The clues in the name: tetra means 4, thus CBr4
The formula of carbon tetrabromide is CBr4.
This chemical formula is CBr4.

There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
Since there is one carbon atom per mole in carbon tetrafluoride, the answer is 3.27 times Avogadro's Number or about 1.97 X 1024 atoms.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.

4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
A mole of a substance has 6.022 E23 things of that substance. So 3 moles of Carbon-12 has 1.806 E 24 atoms.
Convert 1.35 × 1024 atoms of carbon to moles of carbon
There are 9.33 moles of carbon in 5.62 atoms of carbon.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
Since there is one carbon atom per mole in carbon tetrafluoride, the answer is 3.27 times Avogadro's Number or about 1.97 X 1024 atoms.
