Question

Calculate no. Of atoms of hydrogen in 34g of NH3

Answer 1

34g atoms of NH3 contains 2 molecules Of NH3

that is mass of N = 14

H=1: 3H=3 So 1 molecle NH3 is 17 g . So 34g Contains 2 NH3. So 6 Hydrogen And 2 Nitrogen Atoms Are there

Answer 2

Answer:

12.04×10power23

Explanation:

formula is》》 Number of atoms = number of moles×Na(Avagadro number i.e 6.02×10power23)

Number of mole is given by

Mass in gram divided molecular mass

34÷17=2 moles

Now putting this in above formula

No. of atoms= 2×6.02×10power23=12.04×10power23
