YOu need the avogadro number, which is 6,02 * 10^23 particles/mole.
so you have that amount of particles is 1 mole of any gas if it is under normal pressure and temperature, so you only have to do 5 * (6,02 * 10^23)=3,01* 10^22.
done!
6.022 x 1023 x 5 = 3.011 x 1024
In 5 moles of oxygen molecules (O2) there would be
6.022 x 1023 x 5 x 2 = 6.022 x 1024
5. The number of molecules would be 3 x 1024
10 moles of oxygen atoms or 5 moles of oxygen molecules.
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
The answer is: Number of Avogadro x 5 = 30,11070645.1023 atoms.
1 mole of lithium has 6.023 x 1023 atoms. So 5 moles will have 30.115 x 1023 atoms
There are 6 atoms of oxygen represented by this.
Diphosphorus pentoxide has 5 oxygen atoms per molecule according to the given prefix. So, 5 moles of it will be 5 x 5 x (6.022x10^23) = 1.51x10^25 oxygen atoms.
10 moles of oxygen atoms or 5 moles of oxygen molecules.
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
In one mole of aluminum III oxide (Al2O3), there are 2 moles of aluminum atoms (since there are 2 aluminum atoms in each formula unit of Al2O3) and 3 moles of oxygen atoms. Therefore, one mole of aluminum III oxide contains 2 + 3 = 5 moles of atoms. Avogadro's number (6.022 x 10^23) of atoms can be found in one mole of any substance.
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
5 moles H2O (1 mole O/1 mole H2O)(6.022 X 1023/1 mole O)(1 mole O atoms/6.022 X 1023)= 5 moles oxygen atoms=================( as you see this is a formal set up that you do not need to use fully as Avogadro's number is over itself as a form of one )5 moles H2O (2 moles H/1 mole H2O)6.022 X 1023/1 mole H)(1 mole H atoms/6.022 X 1023)= 10 moles hydrogen atoms====================
very roughly 5 moles...avagadros number = 6.022 x 1023 just devide 30 by this number
The nunber of moles of oxygen is 2,5.
The balanced chemical equation for the reaction between aluminum (Al) and oxygen (O2) is 4 Al + 3 O2 → 2 Al2O3. This means that 3 moles of O2 react with 4 moles of Al. Therefore, to react with 5 moles of Al, you would need (5 moles Al) x (3 moles O2 / 4 moles Al) = 3.75 moles of O2.
The answer is: Number of Avogadro x 5 = 30,11070645.1023 atoms.
1 mole of lithium has 6.023 x 1023 atoms. So 5 moles will have 30.115 x 1023 atoms
