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.
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.
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.
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
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.
Yes, the formula is CaCO3. There are three oxygen atoms, 1 calcium atom and one carbon atom.
One atom of calcium weighs approximately 40 atomic mass units.
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.

The mass of a Calcium-40 atom is approximately 40 atomic mass units (amu). This value represents the total mass of the protons, neutrons, and electrons in the atom.
The molar mass of calcium oxide is 56.077 grams per mole
one atom of sulphur and one atom of calcium
The mass number of an atom of calcium with twenty protons and twenty neutrons is 40. This is because the mass number is the sum of the protons and neutrons in the nucleus of an atom.
one atom of sulphur and one atom of calcium
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.
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
The element with an atomic mass of 40.078 amu is calcium. Calcium has an atomic number of 20.
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.
