More than Just Lines on a Map: Best Practices for U.S Bike Routes
We use the the realtion M1V1 = M2V2 where M1 and .pdf
1. We use the the realtion M1V1 = M2V2 where M1 and M2 are the molality of
starting and final solutions and V1 and V2 are the volumes of solutions which are required to
take We know that we have 25 ml fo .5 M NaOH solution therefore M1 = .5 M We need to find
what is the volume of first solution (V1) be taken and diluted to 25 ml such that we get our
desired concentration (M2 = 10^-3M) of volume V2 = 25 ml So, .5*V1 = 25*.001 V1 = .05 ml
