I got 2.084973166 mol/L for the concentration, however I just can't figure out sig figs.... would it be 3 or 4? Because does the conversion between mL to L count or are they looked at as an unlimited number of sig figs. Therefore, would the answer be 2.08M or 2.085M?

The following solutions are combined in a calorimeter to determine the enthalpy of the neutralization reaction between a strong base and a strong acid. 100.0 mL sodium hydroxide, NaOH, of unknown concentration an excess of 1.1027 M hydrochloric acid, HCI The experimental value for q is determined to be -11.655 kJ Knowing that the theoretical value of q for any neutralization reaction is -55.90 kJ/mol H2O, determine the concentration of the sodium hydroxide solution. (Give your answer in moles per liter, with appropriate significant digits) Number M
