Final answer:
To find the mass of hydrochloric acid mixed with excess calcium hydroxide, you would need more information about the reaction. Without the initial mass of hydrochloric acid or any other information about the reaction, the mass of hydrochloric acid mixed with excess calcium hydroxide cannot be determined.
Step-by-step explanation:
To find the mass of hydrochloric acid mixed with excess calcium hydroxide, you would need more information about the reaction. The balanced equation for the reaction between hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)2) is 2HCl + Ca(OH)2 -> CaCl2 + 2H2O.
Given the balanced equation, you can determine the number of moles of hydrochloric acid and calcium hydroxide. Then, using the molar mass of HCl, you can convert the moles of HCl to grams.
Without the initial mass of hydrochloric acid or any other information about the reaction, the mass of hydrochloric acid mixed with excess calcium hydroxide cannot be determined.
