Question

calculate the number of moles in 34g of nh3​

Answer 1

Answer:

2 moles

Explanation:

mass of nh3= 34g

molar mass of nh3= 17g/mol

moles = mass of nh3/molar mass of nh3

moles = 34/17

MOLES = 2

Answer 2

Let the no. of moles be X.

Molecular weight of ammonia =17g

17 g - 1 mole

34 g - X

X = 34/17=2 moles

Thus, the no. of moles on 34 g of ammonia is 2 moles.
