A) \[0.04\]
B) \[0.02\]
C) \[0.4\]
D) \[0.2\]
Correct Answer: C
Solution :
\[\because \] 10 litre of urea solution contains area = 240 gm The active mass of urea =? \[\therefore \]1 litre of urea solution contains urea \[\frac{240}{10}=24gm\] \[\therefore \] Active mass \[=\frac{24}{60}=0.4\] [Mol. wt. of urea \[(N{{H}_{2}}CON{{H}_{2}})\] \[=14+2+12+16+14+2=60\]]You need to login to perform this action.
