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.
