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

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the maximum mass of nh3 is nh3 in grams
