This is carbon tetra chloride. there are 0.3636 moles in this mass.
80,0 moles of CO2is equal to 3 520,8 g.
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.
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
211g of carbon dioxide are equal to 4,794 moles.
