Hi! I need this answer really quickly. Thank you!

A 12.345-g sample of a solid mixture, containing both sodium hydroxide (NaOH) and sodium hydrogen carbonate (NaHCO3) was reacted with an excess of 5.00 M hydrochloric acid (HCI). The two balanced chemical equations for the reactions are shown below: molar masses: 40.00g/mol 36.46g/mol 58.44g/mol 18.02g/mol reaction 1: NaOH(s) + HC(aq) NaCl(aq) H20(1) molar masses: 84.01g/mol 44.01g/mol reaction 2: NaHCO3(s) + HCl(aq) NaCl(aq) + H20(1) CO2(9) + The carbon dioxide gas (CO2(g)) produced by the reaction of the HCl with the NaHCO3 in the solid mixture was collected.

Expert Solution
Step 1 : Given

For the produced CO2 gas, 

Volume, V = 1.171 L

Temperature, T = 23.3 °C

                         = (23.3 + 273.15) K

                         = 296.45 K

Gas constant, R = 62.36 L mmHg K-1 mol-1

Pressure, P = 745 mm Hg
