Answer 2

QUESTION:-

Calculate the percentage of nitrogen in urea CO(NH2)2.

ANSWER:-

$\sf{molecular \: mass = 12 + 16 + 2(14 + 2) = 60}$

$\sf{percentage \: of \: nitrogen = } \red{ \frac{mass \: of \: nitrogen \: in \: compound}{molecular \: mass} \times 100}$

$\sf \red{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{28}{60} \times 100}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \boxed{ \sf{ \red{ = 46.67\%}}}}$

$\tt \underline \blue{Hence, \: the \: percentage \: of \: nitrogen \: in \: urea \: is \: 46.67 \%.}$
