Question 26 (4 points) Question 15: A current of 3.25 A was passed through a solution of sulfuric acid for 18 minutes. The hydrogen produced was collected over water at 20°C and 657.5 mmHg (Ptotal) and was found to occupy a volume of 534mL. 2H+ + 2e → H2 Question 15-2: What is the value of Avogadro's number? (At 20°C vapor pressure of water is 17.5 mmHg and Ptotal - PH2O + PH2) 6.02 x 1022 X 5.86 x 1022 X 5.86 x 1023 6.02 x 1023 Question 27 (3 points) Question 16: The actual values for the Avogadro's number is 6.02x1023. Calculate the percent error in this value from above question 15 (Percent error = actual value- experiment value 1/(actual value) x 100%) 1.15 2.66 0.00
