What is molarity os the resulating solution obtained by mixing 2.5 L of 0.5 M urea solution and 500 mL of 2M urea solution ?

Text Solution

Verified by Experts

Molarity of solution on mixing :
`M_(3)=(M_(1)V_(1)+M_(2)V_(2))/((V_(1)+V_(2))`
According to available dete:
`M_(1)=0.5M,V_(1)=2.5L,M_(2)=2M,V_(2)=500mL=0.5L`
`M_(3)=((0.5Mxx2.5L)+(2Mxx0.5L))/((2.5L+0.5L))=((2.25ML))/((3.0L))=0.75M`
