Question

find the number of molecules in 2.24 litre ammonia at STP




I want a clear answer for the question and not from the google​

Answer 1

Answer:

0.6022× 10^-23

Explanation:

here, we given amount in litres...so we use this formula..(wrote above)

so using this formula we can find no of moles than we know 1 mole means 6.022 ×10^23 molecules ..then 0.1 mole means how many molecule ?...by cross multiplication we found this anser....

hope this will help you..

Answer 2

Explanation:

every gas irrespective of its molar mass occupies 22.4L at STP. (AVOGADRO'S HYPOTHESIS)

22.4L===1 mol

2.24L===0.1 mol

1 mol NH3 HAS 4*(AVOGADRO'S number). molecules

0.1 mol has. 4 into AVOGADRO'S number into 0.1 molecules
