In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
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.
Two times Avogadro's number (6.022×10 to the 23)
8.93 1021 atoms equal 0,0148 moles.
5.66 x 10^23 atoms of xenon is equal to 0.094 moles.
5,82 x 1023 atoms of tungsten equal 0,966 moles.
4,515.10e24 atoms of magnesium is equal to 7,5 moles.
0,0178 moles of tin is equal to 0,107.10e23 atoms.
2 moles equals 8 g of helium or 12.046 x 1023 atoms
