Nitrogen reacts with a metal to form a compound in which there are three atoms of the metal for each atom of nitrogen. if 1.486 g of the metal reacts with 1.000 g of nitrogen, what is the calculated atomic mass of the metal?

We are given that:

1 atom N = 3 atom of the metal

1 mol N = 3 mol of the metal

First let us convert the given nitrogen into number of moles:

moles N = 1 g / (14 g / mol)

moles N = 0.071 mol

Therefore the atomic or molar mass of the metal is:

molar mass = 1.486 g / (3 * 0.071 mol)

molar mass = 6.93 g / mol

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

i think its 100.

hope this !
