To find the volume ratios we say m1v1=m2v2

where m1 is the initial molarity, m2 the final molarity, v1 the initial volume, v2 the final volume.in this question m1=2.00M, m2=0.40M v2=150ml

Therefore the expression becomes:  2.00M×v1=0.40M×150mL

                                                           v1=(0.40M×150mL)/2.00M

                                                               =30mL
