For this problem, the Atomic Mass is not required. Take the mass in moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for the units to cancel.
8.00 moles × (6.02 × 1023 atoms) = 4.82 × 1024atoms
0,39 moles of gallium contain 2,34863493423.10e23 atoms.
8.30 moles (NH4)2S (8 moles H/1 mole (NH4)2S)(6.022 X 1023/1 mole H) = 3.99 X 1025 atoms of hydrogen ========================
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
2,2 moles of plutonium: 13,248711938.1023 atoms.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
8
0,666 moles
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
One molecule has four H atoms.So two moles have 8 moles
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
1,638 moles contain 9,864266723766.10e23 atoms.
44 moles of atoms
This is equivalent to 1,4 moles.
20 moles
How many moles of atoms are contained in 382 g Co
1,0.10e9 atoms is equivalent to 0,166.10e-14 moles.
Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
