Question

9. Which of the following contains maximum number of molecules?
(a) 4 g of Oz
(b) 4g of NH3
(c) 4 g of SO2
10. Calculate the number of:​

Answer 1

Answer:

We know that

no of moles= Given mass / molar mass

Explanation:

Since the given mass is same for all ie, 4g

molecules will be inversely proportional to molar mass

02= 32g

nh3=17g

so2=64g

So NH3 will have max molecules
