To find the number of molecules of benzene (C₆H₆) in 1.0 gram, first calculate the molar mass of benzene, which is approximately 78.11 g/mol. Then, divide the mass of benzene by its molar mass: 1.0 g / 78.11 g/mol ≈ 0.0128 moles. Finally, multiply the number of moles by Avogadro's number (approximately 6.022 x 10²³ molecules/mol) to find the number of molecules: 0.0128 moles × 6.022 x 10²³ molecules/mol ≈ 7.71 x 10²¹ molecules.
12, since in one benzene molecule there are 6 atoms in 2 molecules of benzene there will be 6*2 atoms
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
One mole of any substance, including benzene, contains Avogadro's number of molecules, which is approximately (6.022 \times 10^{23}) molecules. Therefore, 1 mole of benzene contains about (6.022 \times 10^{23}) molecules of benzene.
Benzene, C6H6, as shown on the left, is an organic aromatic compound with many interesting properties. Unlike aliphatic (straight chain carbons) or other cyclic organic compounds, the structure of benzene (3 conjugated π bonds) allows benzene and its derived products to be useful in fields such as health, laboratorial, and other applications such as rubber synthesis.

Benzene has a chemical formula of C6H6 This has a molar mass of 78. So one mole has a mass of 78 grams

To completely combust benzene (C6H6), 15 moles of oxygen are used for every 1 mole of benzene. This reaction produces 6 moles of carbon dioxide for every 1 mole of benzene. Therefore, 0.4000 mol of carbon dioxide would require (0.4000 mol)(1 mol C6H6/6 mol CO2)(15 mol O2/1 mol C6H6) = 1.5 moles of benzene to be combusted.
C6H6 is the molecule of benzene and it's molecular weight is 78, calculated as 6 x 12 +6 x 1=78 and you will understand it if you know some basics of chemistry. then, You know that each mole of a molecule weighs exactly those number of grams as much as is its molecular weight. That means if a molecule has 'M' as its molecular weight, then one mole of it weighs exactly M grams when actually weighed using a weighing machine. This means one mole of benzene weighs 78 grams. then 195 grams of C6H6 has (1/78)x195 moles or 195/78 moles in it.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
The molar mass of C2H6 is 30 {(12*2)+(1*6)}. The number of moles(n)=mass/molar mass n=9.3 g/ 30 g mol-1 =0.31 mol. The number of molecules of C2H6 =n* Avogadro number(L)= 0.31*6.022*1023= 1.86682*1023 The no. of atoms in one mole of C2H6=8 The no. of atoms in 0.31 moles of C2H6=8*1.86682*1023 =14.93456*1023 =1.49*1024
There are 3 pi bonds present in benzene (C6H6), which is a cyclic compound with alternating single and double bonds between carbon atoms.
C6H6, also known as benzene, consists of 3 pi bonds. These pi bonds are located in the delocalized pi electron cloud above and below the ring of carbon atoms.
Molar mass C6H6 = 12.0x6 + 1.00x6 = 72 + 6 = 78 g/mole12.7 moles x 78 g/mole = 990.6 grams = 991 g (to 3 significant figures)
One mole of any substance, including benzene, contains Avogadro's number of molecules, which is approximately (6.022 \times 10^{23}) molecules. Therefore, 1 mole of benzene contains about (6.022 \times 10^{23}) molecules of benzene.
There are 12 sigma bonds in C6H6, as each carbon atom forms sigma bonds with two other carbon atoms and one hydrogen atom in the benzene ring structure.
You first need to find the mass weight of NH3. wt. of N + (wt. of H)= 14.0067 + 3(1.0067)= 17.03052 Now that you have the mass weight, you divide 15 into 17.03052... 15.0/17.03052 = 0.8807 moles in 15. g of NH3
