The ionic compound, MClx (where M is a metal and Cl is chlorine) has a formula mass of 190 g/mol and a mass percent of chlorine of 74.8%. What is the atomic mass of the element

Explanation:

Formula mass of compound = 190 g/mol

Molar mass of chlorine = 35.45 g/mol

means 1 mole of is present and moles of are present.

So,

Mass of percent of chlorine = 74.8%

Now

Atomic mass of the element M is .

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
