A lot...........

Explanation:

Nitrates are generally very soluble.

This site reports a solubility of over 300*g*L^-1 at laboratory temperature. The figure could be even more than this because the quoted value represents a "saturated solution", and "supersaturation", such that the solvent HOLDS more solute than would be in equilibrium with undissolved solute, is a real possibility.
