Question

calculate the number of moles in 34 gram of Nitrogen hydrogen 3

Answer 1

hiiiii mate

given mass of NH3 = 34g


molar mass of NH3 is= 14+1×3=17g/mol

mole = given mass/molar mass

mole =34/17=2

Answer 2

Answer: hi !!!

Here is your answer!!

NH3

N=14u

H=1u =1×3 =3

So 14+3=17

Number of moles = given mass

_________

molar mass

Explanation: 17 is the molar mass

Given masses 34 grams

34 /17 = 2
