Stella is measuring the heat of neutralization when aqueous solutions of HCl and NaOH are combined in a coffee cup calorimeter. She combines 50.98 mL of aqueous 1.00 M HCl and 29.77 mL of aqueous 1.00 M NaOH in a coffee cup calorimeter (mass of the coffee cups + the stir bar = 99.70 g). What is the mass of the solution after mixing, in g, assuming the solution has the same density as pure water (d =1.00g/mL)?

CHM2045L student Stella is measuring the heat of neutralization when aqueous solutions of HCl and NaOH are combined in a coffee cup calorimeter. She combines 46.00 mL of aqueous 1.00 M HCl and 37.72 mL of aqueous 1.00 M NaOH in a coffee cup calorimeter (mass of the coffee cups + the stir bar = 92.27 g). What is the mass of the solution after mixing, in g, assuming the solution has the same density as pure water (d =1.00g/mL)? Express your answer to two digits after the decimal. Do not use units (i.e. g) in your answer.

In a coffee cup calorimeter, 20.0 mL of 2.00 M NaOH and 20.0 mL of2.00 M HCl are mixed. Both solutions were originally at 22.4 C.After the reaction, the final temperature is 33.8 C.
HCl (aq) + NaOH(aq) H2O(l) + NaCl(aq) + heat.
Heat lost by the reaction + heat gained by the NaCl solution =0
q lost + q gained = 0 q gained = (s) (m) (?T)

(A) Calculate the volume of NaCl(aq) (this will be the volume ofthe solution in the calorimeter).
(B) Given that the density of 1.00 M NaCl is 1.03 g/mL, calculatethe mass of the NaCl(aq).
(C) Calculate the ?T for the NaCl(aq).
(D) Given that the specific heat capacity of 1.00 M NaCl(aq) is3.87 J/gC, calculate the heat gained by the solution (qgained)
q gained
Given that 25.0 mL of 2.00 M NaOH and 25.0 mL of 2.00 M HClreacted. Calculate the number of moles of either NaOH or HCl thatreacted. Hneutralization is the heat for the reaction in units ofkJ/mole.
Calculate Hneutralization. (Pay close attention to the sign)
