PLS HELP 10 POINTS!! Round all values to the nearest whole number.
Find zinc (Zn) on the periodic table.
Zinc has protons, neutrons, and electrons.

30 protons

35 neutrons

30 electrons

A rule of thumb for these numbers, the amount of protons are equal to the amount of electrons if they are not ions. Neutrons are the atomic mass of the element subtracted by the amount of protons. Hope this helped!

6.022  ×10(index 23) / 7.5 = 0.8293 ×10(index 23)

Explanation:

molar mass of C =  12gmol

therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)

∴12g/6.02210(index 23) ×1.6g
