How many molecules (not moles) of nh3 are produced from 5.85×10−4 g of h2?

The number of moles is given by:

Mass of hydrogen, =    (given)

Molar mass of hydrogen, =

Number of moles of hydrogen,   =

Reaction between to form is:

From the reaction it is clear that 3 moles of hydrogen gives 2 moles of ammonia and 1 mole of nitrogen gives 2 moles of ammonia .

So, of gives:

Number of moles of ammonia, =

Since, in one mole of ammonia, there are molecules of ammonia, .

So, number of molecules in of ammonia, is:

Hence, the number of molecules of ammonia produced by of is .
