To prepare a 10.0% sodium nitrate solution, 10.0% of the solution's mass must be sodium nitrate. Therefore, for a 50.0 g solution, 5.0 g is sodium nitrate (10% of 50.0 g). The mass of water required is the total mass of the solution minus the mass of sodium nitrate, which is 50.0 g - 5.0 g = 45.0 g.
