You can work this out by dividing the molecular mass of calcium, 40, by Avogadros
number, 6.02214129(27)×1023 mol−1
This will give you the answer as the molecular mass of an element is the
combined weight of the number of atoms that make up one mole, which is the same
as Avogadros number.

What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
How many times an atom of calcium is heavier than an atom of oxygen?
Average atomic mass of Ca = 40.1 Average atomic mass of O = 16.0 Mr(Ca)/Mr(O) = 40.1/16.0 = 2.51 Thus the calcium atom is about 2.5 times heavier than the oxygen atom.
How many calcium atoms are in a molecule of calcium carbonate (CaCO3)?
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
Does calcium carbonate contains five atoms in its formula?
Yes, the formula is CaCO3. There are three oxygen atoms, 1 calcium atom and one carbon atom.
What does one atom of calcium weigh?
One atom of calcium weighs approximately 40 atomic mass units.
What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
