There is no atom with that mass. Even hydrogen, the lightest element, has an Atomic Mass of 1.674 x 10 ^ -21 g
10.3224 g/mol
The mass an atom of technetium isotope 98 is 16,27.10e-23 g.
1 mole of H weights 1.008 g 1 mole = 6.02 x 10^23 particles Mass of 1 atom = 1.008 g / 6.02 x 10^23 = 1.67 x 10^-24 g
Divide 40g by the mass of one atom to find the number of argon atoms.
Mass of an atom = Mass of proton + Mass of neutron
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
This mass is 38,36.10e-23 g.
16 g / mol
10.3224 g/mol
The mass an atom of technetium isotope 98 is 16,27.10e-23 g.
40g
Atomic mass and mass of an atom are somehow different from one another. Atomic mass of carbon will be 12. But mass of one carbon atom will be 1.992 x 10-23 g. As we say atomic mass as 12, it means that it will be 12 times as that of hydrogen atomic mass. If we say 12 g of carbon then it will be considered as gram atomic mass of carbon. Each gram atomic mass of an element will have 6.023 x 1023 number of atoms. 6.023 x 1023 is known as Avogadro's number. Gram atomic mass is also termed as one gram mole. So 6.023 x 1023 atoms weigh 12 g. Then one atom's mass ie mass of one atom will be 12/ 6.023 x 1023 = 1.9923626 x 10-23 g.
mass (g) = atomic wight / Avogadro's number Avo = 6.022x10^23
1 mole of H weights 1.008 g 1 mole = 6.02 x 10^23 particles Mass of 1 atom = 1.008 g / 6.02 x 10^23 = 1.67 x 10^-24 g
Divide 40g by the mass of one atom to find the number of argon atoms.
The atomic mass of argon is 4 g. So one atom of argon will weigh 0.004 kg
7.60x10^-2 g
