Question

find molarity of 20%of urea solution in aqueous solution.
​

Answer 1

Explanation:

$\fbox{★Given}$

• 20% w/v urea solution $\longrightarrow$ 20g urea in 100mL solution
• Solute=20g
• solvent=100-20=80g.
• volume=100mL

$\fbox{★To find}$

• Molarity

$\fbox{★solution}$

$[tex]\textsc {Molarity} [tex]=\frac{\text number \,of \,moles\, of \,solute}{volume \,of \,solution\, (L)}$
