Homework Answers
Dilution factor :-
Volume of the sample/ total volume (sample volume+Dilutent Volume). Example .1mL/.1mL+9.9mL= 0.1mL/10mL= 10^-2. Does not have units.
1. 5ml sample added to 95ml diluent
= 5ml / 5ml+ 95ml = 5/100= 0.05
2. 20ml sample added to 180ml of diluent
= 20ml/20ml+ 180ml = 20/200 = 0.1
3. 40ml of sample added to 200ml of diluent
= 40ml /40ml+ 200ml = 40/240 = 0.16
4. 2ml of sample added to 10ml of diluent
= 2/ 12 = 0.16
