How many nitrogen atoms are in 4.24 x 1022 molecules of Ca (NO3)2 ?

                       8.48 × 10²² atoms of Nitrogen

Explanation:

                   Calcium Carbonate is an ionic compound made up to Calcium (Ca²⁺) and Nitrate (NO₃⁻) ions. Also, the subscript 2 after the closed bracket after NO₃ specifies that there are two moles of NO₃⁻ in calcium nitrate compound. Hence, in total we can say that this compound contain,

                                    1 atom of Calcium

                                    2 atoms of Nitrogen

                                    6 atoms of Oxygen

Therefore,

When,

              1 molecule of Ca(NO₃)₂ contains  =  2 atoms of Nitrogen

Then,

   4.24 × 10²² molecules of Ca(NO₃)₂ will contain  = X atoms of Nitrogen

Solving for X,

                      X  =  2 atoms × 4.24 × 10²² molecule / 1 molecule

                      X =  8.48 × 10²² atoms of Nitrogen

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
