What is the mass of one atom of calcium?

Answer 1

You can find the molar mass on the Periodic Table under Calcium. Remember there are 6.022 X 10^23 atoms in one mole. So just divide the molar mass of Ca by Avogadros number and done.

Answer 2

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.

Answer 3

40.078 u

In the future, you should make reference to a periodic table. If you do not have one at hand, type in "Periodic Table" in any search engine and you will find one.

Answer 4

The molar mass of calcium is 40 grams per mole. Dividing this by Avogadro's number gives an approximate mass of 6.6 E(-23) grams per atom.

Answer 5

Do you mean one mole? The mass in grams of one mole of any given element can be found on the periodic table. Ca would be 40.08

Answer 6

The mass of one atom of calcium is approximately 40 Atomic Mass units (u) or 40 grams per mole (g/mol).

Answer 7

mass=40gm

Answer 8

40.078
