The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
I think its me myself
Sodium's atomic mass is 23. :)
2.3 = 23/10 and reduces to: 2 3/10
(17-4)+10=23 13+10=23
The mass of Mars is approximately 6.42 x 10^23 kilograms.
To find the mass of 3.01 x 10^23 formula units of Fe2O3, you need to calculate the molar mass of Fe2O3, which is 159.69 g/mol. Then, multiply this molar mass by Avogadro's number (6.022 x 10^23 mol^-1) to get the mass of one mole of Fe2O3. Finally, multiply this result by 3.01 x 10^23 to find the mass of 3.01 x 10^23 formula units of Fe2O3.
To calculate the mass of 3.011 x 10^23 nitrogen atoms, first find the molar mass of nitrogen which is 14.01 g/mol. Then, divide the number of atoms by Avogadro's number (6.022 x 10^23) to get the number of moles. Finally, multiply the number of moles by the molar mass to find the mass of the atoms. The calculation would be 3.011 x 10^23 / 6.022 x 10^23 = 0.5 moles, then 0.5 moles x 14.01 g/mol = 7.005 grams.

The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
To calculate the mass of 6.02 x 10^23 atoms of sulfur, you would first find the molar mass of sulfur (32.06 g/mol). Then, you would divide this molar mass by Avogadro's number to get the mass of one sulfur atom (in grams). Finally, multiply this value by 6.02 x 10^23 to find the mass of 6.02 x 10^23 atoms of sulfur.
To find the total mass of 3.01 x 10^23 atoms of helium gas, you need to multiply the number of atoms by the atomic mass of helium. Helium's atomic mass is approximately 4 atomic mass units. So, the total mass would be 3.01 x 10^23 atoms * 4 amu.
2 atoms of lead have greater mass. Lead atoms are heavier than helium atoms, and the small amount of helium given in moles would still have a much smaller combined mass compared to the two lead atoms.
Ganymede, which is one of Jupiter's moons, has a mass of about 1.48 x 10^23 kilograms.
The mass number of this atom is 23, the sum of the number of protons and neutrons.
The mass ratio of an iron atom is 56, since the atomic mass of iron is approximately 55.85 atomic mass units.
13.2 atomic mass units = 2.1919113 × 10-23 grams. (1 atomic mass unit = 1.66053886 × 10-24 grams).
