Question

How many molecules are there in 3.00
moes of NH₃

Answer 1

• No of moles=3mol

Now

No of molecules:

`\\ \sf\longrightarrow No\:of\;moles* Avagdro\:no)`

`\\ \sf\longrightarrow 3(6.022* 10^(23))`

`\\ \sf\longrightarrow 18.066* 10^(23)`

`\\ \sf\longrightarrow 1.8066* 10^(22) molecules`
