Atomic Mass of Na: 23.0 grams
1.50 moles × (6.02 × 1023 atoms) = 9.03 × 1023atoms
To find the number of moles of atoms in 150 g of sulfur (S), first, we need the molar mass of sulfur, which is approximately 32.07 g/mol. The number of moles of sulfur in 150 g can be calculated using the formula: moles = mass (g) / molar mass (g/mol). Therefore, 150 g of S corresponds to about 4.68 moles of sulfur. Since each sulfur atom is a single atom, there are also 4.68 moles of atoms in 150 g of sulfur.
1,638 moles contain 9,864266723766.10e23 atoms.
20 moles
This is equivalent to 1,4 moles.
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.
1,0.10e9 atoms is equivalent to 0,166.10e-14 moles.
8.93 1021 atoms equal 0,0148 moles.
Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
2,50 moles of silicon contain 15,055352142.10e23 atoms.
