What volume of H2 gas, measured at 57˚C and 850 torr, can be obtained by reacting 10.00 g zinc metal with 300. mL of 0.350 M HCl? Zn (s) + 2HCl (aq) → ZnCl2 (aq) + H2 (g) To do this, answer the following questions: i. the limiting reactant is___________ ii. the maximum number of moles of H2 (g) that can be produced from this reaction is____________ (answer to 4 decimal places) iii. now that you have the moles of H2, which equation will you use to calculate the volume of H2 (g) that can be produced from this reaction? iv. the volume of H2 (g) that can be produced from this reaction is _______________ (answer to 3 decimal places) () Provided molar mass, use as needed Zn = 65.39 g/mol HCl= 36.46 g/mol H2 = 2.016 g/mol ZnCl2 = 136.29 g/mol
