Question

Fifty cubic centimeters urine is added to 100mL diluent.give the dilution of the solution.what is the urine to total volume ratio?

Answer 1

If 100cm³ of the diluent has 50cm³ of urine

$\therefore$ 1000cm³ of diluent has $\frac{1000×50}{100}=500cm^3 of urine$

$\therefore$ Concentration of solution is 500cm³ of urine /1000cm³ of diluent

Ratio of urine to silent =500cm³ :1000cm³

=1:2
