What is the mass of a calcium atom compared with the mass of a helium atom?
5
What is the symbol for the atom that has 40 electrons?
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
What is the mass of calcium atom compared with the mass of helium atom?
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
How many protrons are in a calcium's atom?
it has 40
How can the mass of an atom from the periodic be represented in respect to moles?
The mass of a single atom would be the mass of one mole of that element, divided by Avogadros number. So for example calcium, Ca, would be 40/6.02214129×1023 mol−1
How do you find the percentage of calcium in calcuim bicarbonate molecule?
Mass percent = Mass of part / Total Mass * 100% Atomic mass of calcium = 40 Molecular mass of calcium bicarbonate = 162 40 / 162 *100 = 24.7% Calcium by weight in a Calcium Bicarbonate Molecule.
