What's the M of the diluted solution? That will be 5.8M x (45.8/1000) = about 0.26M
How many mols in 15.0 g KNO3? That is 15.0/molar mass KNO3 = about 0.15 moles.
So what volume of the diluted solution do we need to make 0.15 moles.
M = moles/L
0.26 M = 0.15 moles/L
L = about 600 mL.
Check my work. It's late and past time for my bed.
