25.0 g C10H8N2O2S2 ( 1 mole C10H8N2O2S2/252.324 g)(10 mole C/1 mole C10H8N2O2S2)(6.022 X 1023/1 mole C)
= 5.97 X 1023 atoms of carbon
---------------------------------------
The number of carbon atoms is 0,588.10e23.
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
72.0 grams Carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 3.61 X 10^24 atoms of carbon
28.5 g (6.02 x 1023 at / 12.01 g) = 1.43 x 1024atoms
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
The number of carbon atoms is 0,588.10e23.
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
Atomic mass of carbon: 12.0 grams1.90 grams × (6.02 × 1023 atoms) / (12.0 grams) = 9.53 × 1022 atoms C
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
The answer is 13,367.1010e+23 atoms.
0,666 moles

3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
9.00 grams carbon 13 ( 1 mole C13/13.00355 grams)(6.022 X 1023/1 mole C13) = 4.17 X 1023 atoms of carbon 13 -------------------------------------------
2.6 grams graphite ( just carbon ) (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 1.3 X 1023 atoms of carbon in that mass graphite ================================
3.121x10-5 Grams of Na2CO3
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
