how to make a dilution series

Question 1

how to make a serial dilution

Answer 1

volume of stock solution= required conc x final volume needed divided by conc of stock solution

volume of water = final vol needed - vol of stock solution

Question 2

how would you carry out a serial dilution for a 1 mole stock solution
and the required conc is 0.3 and final volume is 50ml

Answer 2

0.3 x 50/ 1 = 15 ml stock solution

volume of water= 50 ml - 15ml
= 35 ml
