44 moles of atoms
4 moles of oxygen atoms are present in 4 moles of H2O
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
How many moles of HCl are present in 154 g of HCl?
2,2 moles of plutonium: 13,248711938.1023 atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
48,177 134 32.1023 atoms
If the oxygen is present as oxygen atoms there are 2 moles. If the oxygen is present as oxygen molecules you have one mole.
4.2 moles of CS2 contain 8,4 moles sulfur.
0.0845 moles of tungsten is equal to 0,50887.10e23.
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
6.02 x 1023 carbon atoms
There is 25.0 moles Oxygen
4 moles of oxygen atoms (being present in 4 moles of H2O) and, so: 4 moles of oxygen atoms is 4*6.02*1023 = 24.1*1023 molecules ATOMS of oxygen
2,00 moles of ammonia (NH3) have 3 moles of hydrogen.
There is not enough information to answer the question as it is asked. There is one molecule present. There are 5 atoms present in that molecule. To find out how many moles are present we would need to know what mass is present.
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
2,3 g of Na is equal to 0,1 moles.
there are 500210 g of atoms
One molecule has four H atoms.So two moles have 8 moles
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
divide by Avogadro's number 3.25E24 / 6.022E23 = 5.40 moles
It is 1.20 x 10 ^23.You multiply 2 moles times 6.022x10^23 atoms, which is Avogrado's number.
In each molecule of water there is one hydrogen atom. In 2.69 moles, there are 8.124 E23 molecules, so there are the same number of atoms of hydrogen present.
30 x 6.022 x 1023 = 1.81 x 1025 atoms of carbon moles x Avogadro's constant = number of atoms
