For the reaction 3NO2(g)+H2O(l)→2HNO3(aq)+NO(g),
What is the mass of HNO3 that is produced when 24.45 g of NO2 and 24.45 g of H2O react

Expert Solution

number of moles = weight of substance / molar mass of substance

number of moles of NO₂ = 24.45g / 46 g/mol = 0.5315 moles

number of moles of H₂O = 24.45g / 18g/mol = 1.358 moles

limiting reagent is the NO₂

From the reaction,

3 moles of NO₂ produces 2 moles of HNO₃

then 0.5315 moles of NO₂ produces (2 * 0.5315) / 3 = 0.3543 moles

therefore mass of HNO₃ produced = number of moles * molar mass

= 0.3543mol * 63.01g/mol

= 22.326 grams
