∙ 11y agoTo calculate the number of moles equivalent to 5.75x10^24 atoms of Al, you would first need to determine the molar mass of Al, which is approximately 26.98 g/mol. Then, you would use Avogadro's number (6.022x10^23 atoms/mol) to convert the number of atoms to moles. This would give you approximately 96.1 moles of Al.
To find the number of moles of copper, divide the number of atoms by Avogadro's number (6.022 x 10^23). Therefore, 3.44 x 10^23 atoms of copper is equivalent to 0.571 moles of copper.
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.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
To find the number of moles, you need to divide the given number of iron atoms by Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Therefore, for 5.22 x 10^22 iron atoms, the number of moles would be approximately 0.0867 moles.
There are 6.3 moles of H atoms in 2.1 moles of H3PO4. This is because there are three moles of H atoms in one mole of H3PO4.
This is equivalent to 1,4 moles.
1,0.10e9 atoms is equivalent to 0,166.10e-14 moles.
3,2x10e22 atoms of sulfur is equivalent to 0,053 moles.
8,23.1023 atoms Mg is equivalent to 1,366 moles.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
5.75x10^24 atoms x 1 mole/6.02x10^23 atoms = 9.55 moles of Al
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
To convert atoms to moles, you divide by Avogadro's number, which is 6.022 x 10^23. 1.2 x 10^24 atoms of helium is equivalent to 2 moles of helium.
4,5 moles of copper are equivalent to 285,957 g.
To find the number of moles of copper, divide the number of atoms by Avogadro's number (6.022 x 10^23). Therefore, 3.44 x 10^23 atoms of copper is equivalent to 0.571 moles of copper.
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.
There are 2.75 x 10^23 atoms in 0.455 moles of lead. This is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles.
