2 HNO3(aq) +
K2CO3(aq) → 2
KNO3(aq) +H2O(l)
+CO2(g)
Suppose that a 36.9-mL volume of HNO3 solution reactions
completely with 35.0 mL of aqueous K2CO3. The
volume of CO2 formed is 164. mL at 16.°C and 747.
mmHg.
What is the molarity of the HNO3 solution?
Firstly I have calculated the number of moles of HNO3 required to produce 0.006797 mol of CO2 . Then volume of HNO3 is given so I applied the formula of molarity .
