I have a DCPIP solution of 3.37*10^-3 M

I need it to be 1.7*10^-3 M

 

I want 100ml of it.

 

So how much water and how much of the 3.37*10^-3 M DCPIP do I have to put in.

 

Also, anybody know a website or formula so I know for next time...

 

Thanks a lot. By the way, 3.37/1.7=1.98235 and 1.7/3.37=0.504451

It's roughly 50ml of each, how accurate do you need it?

 

i'd like it accurate please, so that i can get good marks for my titration investigation

Actually I think it will be 50-50.

 

50.4451 ml of DCPIP and 49.6649 of water to be exact.

 

Is this correct? Please...
