How many moles of carbon and hydrogen are there in 5 moles of octane?
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).
How many moles and number of atoms are there in 44 grams of H2O S 32 O 16 and H 1?
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 atomic number of 10 have the same number of electrons as each what except?
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
How many grams are in 1.5 moles of water?
There are approximately 27 grams in 1.5 moles of water.
How are all F atoms different from each other?
They are not! The whole point about atoms of an individual element is that they are all essentially the same. There may be a small number of varieties - isotope - in which the number of neutrons varies, but that is the only difference.
How many moles of H are in 2 mol of c8h18?
There are 18 moles of hydrogen atoms in 2 moles of C8H18 because each mole of C8H18 contains 18 hydrogen atoms.
How many moles of carbon are present in 4.37x1018?
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
How many moles are of nitrogen are in 12 moles of trinitrotoluene?
3 x 12 = 36 moles of Nitrogen atoms N or 18 moles of Nitrogen molecules N2
How many moles of carbon and hydrogen are there in 5 moles of octane?
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).
How many moles of nitrogen are required to produce 18 mol of ammonia?
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.
How many atoms of H are in 2 mol of c8h18?
There are 16 hydrogen atoms in 2 moles of C8H18. Each molecule of C8H18 contains 2*8=16 hydrogen atoms.
How many atoms are in 3 mole of carbon?
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 million argon atoms are how many moles of argon 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.
How many moles and number of atoms are there in 44 grams of H2O S 32 O 16 and H 1?
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
What elements have 10 neutrons in their neuclius?
Oxygen-18, fluorine-19 and neon-20 atoms have 10 neutrons each.
How many atoms are present in 1 milligram of oxygen?
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
How many moles of sodium can be made from 4.37 x 1018 atoms of sodium?
To find the number of moles, divide the number of atoms by Avogadro's number, which is 6.022 x 10^23. So, 4.37 x 10^18 atoms / 6.022 x 10^23 atoms/mol = approximately 7.26 x 10^-6 moles of sodium.
