There are a flask, and burette containing an acid, and a base, respectively The first, a flask contains a solution of 10 mL of an unknown acid and 0.15 mL of PhenolphthaleinThe second, a burette containing 52 mL of 10.0 M NaOH. The flask now contains a total of 10.15mL solution of an unknown acid, and 0.01 mL of NaOH is dropped by a burette.The flask turned from colorless to pink when the solution is 12.210 after receiving drops from the burette which means a total of 2.06mL of NaOH is needed to turn the inknown acid into pink. What is the concentration of the acid (Please use three significant figures for your answer in M)

I cannot understnad this question because the question is asking the ‘concentration’ but the solution showing just ‘number of moles’. Did I misunderstnading??

Give detailed Solution..don't give Handwritten answer

Data Analysis and Interpretation 1. Marble is calcium carbonate, CaCO3. Its reaction with hydrochloric acid is CaCO3(s)+ 2HC1(aq) → CaCl2(?)+ CO2(g) + H2O(!) What was the gas produced when marble reacted with HC1? Using the solubility rules, determine the physical state for CaCl2, explain which rule you used. id Do these
