Question

what mass of Nitrogen will be required to produce 6.022 into 10 to the power 24 molecules of ammonia by the following reaction
N2 +3H2----------> 2NH3

Answer 1

Answer:

w=140g

Explanation:

we have,

no.of molecules=n*No

=>6.023*10^24=n*60.23*10^23

=>n=10

from the reaction,

1moles of N2 produce 2mole of NH3

therefore,

10moles of NH3 required=5moles N2

hence,

weight=M*5

w=28*5

=>w=140g
