For this problem, the Atomic Mass is not required. Take the number of atoms and divide it by Avogadro's constant, 6.02 × 1023. Multiply by one mole for the units to cancel.
6.00 × 109 atoms / (6.02 × 1023)= 9.97 × 10-15moles
To calculate the number of moles from atoms, you use Avogadro's number, which is 6.022 x 10^23 atoms per mole. Given that 2 billion is 2 x 10^9, you would divide 2 x 10^9 atoms by Avogadro's number to get the number of moles. Therefore, 2 x 10^9 cobalt atoms is equal to approximately 3.32 x 10^-15 moles of cobalt.
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
To determine the number of moles in 382 g of cobalt (Co), first calculate the molar mass of cobalt, which is approximately 58.93 g/mol. Then, divide the given mass by the molar mass to obtain the number of moles. Moles = 382 g / 58.93 g/mol = approximately 6.48 moles of Co atoms.
One billion equals 109. A mole of magnesium contains Avogadro's number of magnesium atoms. Therefore a billion atoms constitutes 109/(6.022 X 1023) or about 1.66 X 10-15 mole.
To convert 4.76 moles of cobalt into grams, you need to multiply by the molar mass of cobalt, which is approximately 58.93 g/mol. Therefore, 4.76 moles of cobalt is equal to 281.52 grams of cobalt.

26,3 g cobalt is equivalent to 0,446 moles.
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.
