Brainliest A 54.6 mL sample of HCl is titrated with NaOH. If 26.5 mL of 0.255 M NaOH is needed to reach the endpoint, what is the concentration (M) of the HCl solution?

NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
