Question

calculate the number of moles in 34g of nh3​

Answer 1

Answer:

mass of nh3= 34g

molar mass of nh3= 17 g/mol

therefore moles = mass of nh3/ molar mass of nh3

moles = 34/17

moles =2

Answer 2

Answer:Let the no of the mole b X

Molecular weight of ammonia = 17 g

17 g - 1 mole

34 g - x

X = 34/17 = 2 mole

Thus the no of mole on 34 g of ammonia is 2 mole .
