How many moles of Ca are in 3.75 x 1025 atoms of Ca? Group of answer choices 3.75 mol 0.016 mol 2.26 x 1049 mol 62.3 mol

62.3 moles of Ca

Explanation:

1 mole of a substance is defined as 6.022x10²³ particles of this substance. For example:  

1mol of electrons = 6.022x10²³electrons  

1mol of atoms = 6.022x10²³atoms

1 mol of molecules = 6.022x10²³ molecules

And 1mol of atoms of Ca = 6.022x10²³ atoms of Ca

That means 3.75x10²⁵ atoms of Ca are:

3.75x10²⁵ atoms of Ca * (1 mole of Ca / 6.022x10²³ atoms) =

62.3 moles of Ca

Ametal with a large number of free flowing electrons most likely has good conductivity

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
