Question

How many molecules are present in 100 g sample of nh3?

Answer 1

Answer:

35.42×10²³

Explanation:

No moles of NH3 in 100g is

No of moles = 100g/17gper mole

                     = 5.88 moles

1 mole of NH3 has molecules= 6.022 ×10²³

then 5.88 moles will have molecules =6.022×10²³×5.88

                                                            = 35.42×10²³
