glad I could help
Carbon tetrachloride has chemical formula CCl4 and molecular mass 153.8
Amount of CCl4 = 8.52/153.8 = 0.0554mol
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
384.5g
Balanced equation. C + 2Cl2 -> CCl4 10 grams carbon (1 mole C/12.01 grams)(1 mole CCl4/1 mole C)(153.81 grams/1 mole CCl4) 128 grams carbon tetrachloride produced -----------------------------------------------------
To find this answer you multiple Avogadro's number, 6.02x10^23, by the number of moles, 5.8, to get 3.4916x 10^24.
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
384.5g
Balanced equation. C + 2Cl2 -> CCl4 10 grams carbon (1 mole C/12.01 grams)(1 mole CCl4/1 mole C)(153.81 grams/1 mole CCl4) 128 grams carbon tetrachloride produced -----------------------------------------------------
0,666 moles
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
450 moles of C2H4 contain 10.815,43 g carbon.
To find this answer you multiple Avogadro's number, 6.02x10^23, by the number of moles, 5.8, to get 3.4916x 10^24.
2,55 moles of the compound CO have 71,4 grams.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
