Quantitative analysis

The equation for the reaction between sodium hydroxide solution and dilute nitric acid is:

\text{NaOH} + \text{HNO}_3 \rightarrow \text{NaNO}_3 + \text{H}_2\text{O}

Calculate the percentage atom economy for the production of sodium nitrate (the desired product) in this reaction.

Relative formula masses ( $M_r$ ):

$NaOH=40.0\text{NaOH} = 40.0$
$HNO3=63.0\text{HNO}_3 = 63.0$
$NaNO3=85.0\text{NaNO}_3 = 85.0$
$H2O=18.0\text{H}_2\text{O} = 18.0$

Give your answer to one decimal place.
