The mass number of an atom of calcium with twenty protons and twenty neutrons?
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.
What does one atom of calcium weigh?
One atom of calcium weighs approximately 40 atomic mass units.
The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.
What is calcium rounded mass number?
Calcium is a metal element. Atomic mass of it is 40.
How many moles are in 3.75 grams of calcium?
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.
The mass number of an atom of calcium with twenty protons and twenty neutrons?
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.
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.
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.
What does one atom of calcium weigh?
One atom of calcium weighs approximately 40 atomic mass units.
The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.
What is the mass of a calcium atom compared with the mass of a helium atom?

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 atomic mass of Ca-43?
The atomic mass of Ca-43 is approximately 43 amu (atomic mass units). This value represents the total mass of an atom of calcium-43, taking into account the protons, neutrons, and electrons that make up the atom.
How many protrons are in a calcium's atom?
it has 40
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.
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
Mass number of 19?
The mass number of an atom is the total number of protons and neutrons in its nucleus. For an atom with a mass number of 19, it would have 19 total protons and neutrons combined. This atom could be potassium-40 (19 protons and 21 neutrons) or calcium-40 (20 protons and 20 neutrons), for example.
