The equation for the reaction between sodium hydroxide solution and dilute nitric acid is:
NaOH+HNO3→NaNO3+H2O \text{NaOH} + \text{HNO}_3 \rightarrow \text{NaNO}_3 + \text{H}_2\text{O} NaOH+HNO3→NaNO3+H2OCalculate the atom economy for the production of sodium nitrate from sodium hydroxide and nitric acid.
(relative formula masses: NaOH=40.0\text{NaOH} = 40.0NaOH=40.0, HNO3=63.0\text{HNO}_3 = 63.0HNO3=63.0, NaNO3=85.0\text{NaNO}_3 = 85.0NaNO3=85.0, H2O=18.0\text{H}_2\text{O} = 18.0H2O=18.0)
