Just the same (more or less) as you'd make any 20% solution - do you mean w/w , w/v, ??? Note the reactivity of Borohydride too, so some solvents may not be a good idea.

Experience is something you don't get until just after you need it.

How about reaction between water and Sodium Borohydride?
If that reaction is dangerous, what should I do?

What does the MSDS that you've linked to say in section 6?

What do you want us to do, pop round to your Lab and make it for you?

You asked how to make a % solution - we gave you the information;
You asked about reactivity (and supplied a MSDS) - we told you in which sections of the MSDS to look and provided additional information.

What more can we do for you?

Sodium borohydride reacts slowly with alcohols and with water, as long as the pH is basic (high). A good solvent can be ether.
BABOOM!! :o
