The chemical formula for water is H2O; therefore each formula unit has three atoms. Avogadro's number is defined as the number of formula units per mole. Therefore, the answer to the stated question is 3 X 6.022 X 1023 = about 1.8066 X 1024 atoms. (If the value "3" is not considered exact, only one significant digit is justified; in that instance, the answer should be written. as 2 X 1024.
Since ammonia has a chemical formula of NH3, it contains one mole of nitrogen and three moles of hydrogen per mole of ammonia. Therefore, 3 moles of ammonia contain 3 moles of nitrogen and 9 moles of hydrogen atoms.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
3,00 moles of Li have 18,066422571.10e23 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.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
3 x 6.02E23 molecules.
Since ammonia has a chemical formula of NH3, it contains one mole of nitrogen and three moles of hydrogen per mole of ammonia. Therefore, 3 moles of ammonia contain 3 moles of nitrogen and 9 moles of hydrogen atoms.
There are 12 atoms of hydrogen in 3 moles of CH4. CH4 consists of one carbon atom and four hydrogen atoms. Since each mole of CH4 has 4 hydrogen atoms, 3 moles would have 3 * 4 = 12 hydrogen atoms in total.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
To find the number of moles of PCl3, you need to first calculate the number of moles of Cl atoms in 3.68 * 10^25 atoms. There are 3 Cl atoms in each molecule of PCl3, so you divide the number of Cl atoms by 3 to get the number of moles of PCl3.
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
The answer is 3 moles.
1 mole of Li₂O contains 2 moles of lithium (Li) atoms and 1 mole of oxygen (O) atoms. Therefore, in 1 mole of Li₂O, there are a total of 3 moles of atoms.
1.8x10*24
54,0 grams of water is equivalent to 3 moles.
3,00 moles of Li have 18,066422571.10e23 atoms.
