Balance this equation by filling in the blanks for each coefficient. If there is no coefficient, please type the answer as 1. Mg + N2 ---> Mg3N2

3Mg+N2---" Mg3N2 this is the right balance.

Explanation:

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

particle   p is an electron and particle q is a neutron
