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!
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
In one molecule of diphosphorus pentoxide (P2O5), there are 5 oxygen atoms. So, in 5.00 mol of P2O5, there would be 5.00 mol * 5 = 25.00 moles of oxygen 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
There are 6 atoms of oxygen represented by this.
The answer is: Number of Avogadro x 5 = 30,11070645.1023 atoms.
In diphosphorous pentoxide (P4O10), there are 10 oxygen atoms for every molecule. Therefore, in 5.00 moles of diphosphorous pentoxide, there would be 5.00 moles x 10 oxygen atoms = 50.0 moles of oxygen atoms.
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
In one molecule of diphosphorus pentoxide (P2O5), there are 5 oxygen atoms. So, in 5.00 mol of P2O5, there would be 5.00 mol * 5 = 25.00 moles of oxygen atoms.
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.
Ten million atoms / Avagadro's Number, 6.022e23 atoms per mole = 1.66e-17 moles
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====================
Sodium dichromate (Na₂Cr₂O₇) has seven oxygen atoms per formula unit. To determine the number of moles in 5 g of sodium dichromate, we first calculate its molar mass, which is approximately 261.97 g/mol. This means there are about 0.019 moles of sodium dichromate in 5 g. Since each mole contains 7 moles of oxygen atoms, the total number of oxygen atoms is about 0.019 moles × 7 × 6.022 × 10²³ atoms/mole, which equals approximately 7.98 × 10²² oxygen 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
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.
The nunber of moles of oxygen is 2,5.
very roughly 5 moles...avagadros number = 6.022 x 1023 just devide 30 by this number
In 4 moles of magnesium hydroxide, Mg(OH)₂, there are a total of 20 atoms. Each formula unit of Mg(OH)₂ contains 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms, totaling 5 atoms per unit. Therefore, for 4 moles, you calculate 4 moles × 5 atoms/mole = 20 atoms.
