Well, atomic mass of calcium is #40 \ "amu"#.

Explanation:

First of all, I think that your question has an error, as there is no way a calcium atom is #40# times greater than the mass of a carbon-13 atom.

Since a carbon-13 atom has a mass of #13 \ "amu"#, then we would say that the calcium atom would weigh #13*40=520 \ "amu"#.

If we look on the periodic table, even the last element, oganesson, has a predicted mass of #294 \ "amu"#.

Also, if we look at the table, it shows that calcium has an average mass of #~~40 \ "amu"#.
