There is no element with that Atomic Mass, the element that comes the closest is Ununbium with an atomic mass of 277.0.
Calcium is a metal element. Atomic mass of it is 40.
.111456
Density is defined as mass divided by volume, therefore: 100g/25cm3 = 4 g/cm3
Density = about 116.28 g/cm3
There is no element or common compound with a density of 45kg/m3 = 1.047 kg/m3. But it could be a mixture of two or more substances: at least one of which has a higher density and at least one has a lower density.
volume of 35g

volume 43
This element is technetium (Tc).
Answer:The mass number of Potassium is 39 (19 protons and 20 neutrons).However, Potassium has isotopes with mass numbers 40 through 43.
The gram is unit of mass and the litre is a unit of volume.You can dissolve 45 g in what volume you want.
Technetium (element number 43) in 1937.
It is a radioactive scandium isotope - 43Sc with 21 electrons and protons, and 22 neutrons.
