Question

Calculate the mass of 0.5 moles of N atoms

Answer 1

We know that,

No. of Moles = Given mass/Molar mass

=> 0.5 g = Given mass/14 g
=> 0.5 g x 14 = Given Mass
=> Given Mass = 7 g

Answer 2

$\mathsf\red{No. \ of \ moles \ = \ 0.5}$

$\mathsf{Molar \ mass \ of \ N \ = \ 14 \ g}$

$\mathsf{No. \ of \ moles \ = \ Given \ mass \ / \ Molar \ mass}$

$\large\mathsf\purple{Putting \ values}$

$\mathsf{0.5 \ = \ Given \ mass \ / \ 14}$

$\mathsf\blue{Given \ mass \ = \ 7 \ g}$
