A 10 mL sample of human urine was found ...

A `10 mL` sample of human urine was found to have `5 mg` of urea on analysis. Calculate the molarity of the given sample w.r.t. urea. (molecular mass of urea = 60)

Text Solution

Verified by Experts

The correct Answer is:
0.0083 mole/litre
Concentration of urea = 5 mg in 10 `cm^(3)` = `"500 mg L"^(-1)="0.50 g L"^(-1)="0.5/60 mol L"^(-1)="0.0083 mol L"^(-1)`
