Question

No. Of atoms in 34 amu of nh3 is

Answer 1

Answer:

2

Explanation:

Molar mass of NH3 = 17a.m.u.

Given mass = 34a.m.u.

Number of atoms = (34/17)

. = 2

Hope it helps

Answer 2

Given:

Molecular weight of NH₃=34 amu

To find the number of atoms in NH₃

Solution:

Number of molecules (N) in 1 mole(6.022×10^23 molecules) of NH₃=14+1ₓ3=17g

Number of molecules in 34g of NH₃= 6.022×10^23ₓ34/17= 12.044ₓ10^23

Again,

Total number of atoms in NH₃=4

Now,

Number of atoms in 34 grams of NH₃ = 4ₓ12.044ₓ10^23 =4.81×10^24.

Thus, the number of atoms in 34 amu of NH₃ is 4.81×10^24.
