In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
Three moles of N2O4 contains six moles of nitrogen atoms (N) and twelve moles of oxygen atoms (O), since each molecule of N2O4 consists of two nitrogen atoms and four oxygen atoms. Therefore, in total, there are 18 atoms in three moles of N2O4.
H2O: 44g x 1 mol/18 g = 2.44 moles and 2.44 moles x 6.02x10^23 atoms/mole = 1.5x10^24 atomsS-32: 44g x 1mol/32g = 1.375 moles and 1.375 moles x 6.02x10^23 atoms/mole = 8.3x1^23 atomsO-16: 44g x 1 mol/16g = 0.6875 moles and 0.6875 moles x 6.02x10^23 atoms/mol = 4.2x10^23 atomsH-1: 44g x 1mol/1g = 44 moles and 44 moles x 6.02x10^23 atoms/mole = 2.6x10^25 atoms
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
There are approximately 27 grams in 1.5 moles of water.
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
3 x 12 = 36 moles of Nitrogen atoms N or 18 moles of Nitrogen molecules N2
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
Three moles of nitrogen are required to produce 2 moles of ammonia according to the balanced chemical reaction for ammonia synthesis. Therefore, 27 moles of nitrogen are required to produce 18 moles of ammonia.
1 mole of carbon (or 12 g) has 6 x 1023 atoms. So, 3 moles of carbon (or 36 g) has 18 x 1023 atoms
One mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, one million argon atoms would be equivalent to roughly 1.66 x 10^-17 moles of argon atoms.
H2O: 44g x 1 mol/18 g = 2.44 moles and 2.44 moles x 6.02x10^23 atoms/mole = 1.5x10^24 atomsS-32: 44g x 1mol/32g = 1.375 moles and 1.375 moles x 6.02x10^23 atoms/mole = 8.3x1^23 atomsO-16: 44g x 1 mol/16g = 0.6875 moles and 0.6875 moles x 6.02x10^23 atoms/mol = 4.2x10^23 atomsH-1: 44g x 1mol/1g = 44 moles and 44 moles x 6.02x10^23 atoms/mole = 2.6x10^25 atoms
one mole of oxygen = 16grams and is 6.02x10^23 atoms one milligram of oxygen is 0.001 grams. number of moles = mass used/ RMM of compound therefore number of moles = 0.001/16 =6.25x10^-5 moles used. to convert to number of atoms multiply by avagadros number. 6.25x10^-5 * 6.02x10^23 3.763x10^19 atoms
Oxygen-18, fluorine-19 and neon-20 atoms have 10 neutrons each.
1 mole contains an Avagadro number so 4.37 x 1018 divided by 6.023 x 1023 = 0.72555 x 10-5 or 7.2555 x 10-6 moles of sodium
18 atoms in total.
