Note

I'm using rounded numbers. Every periodic table is different. Use yours to correct my approximations.

1 mole of NH3

N = 14

H = 1

3 H = 3

==========

1 mole = 17 grams

Number of moles in 25 grams

moles = given mass / molar mass

moles = ???

given mass = 25 grams

molar mass = 17 grams

n = 25/17

n = 1.47 moles
