Question

What is the ratio of moles H2 gas generated to the moles of metal reacting? The experiment described in the procedure was performed using a sample of Aluminum with HCl(aq). The lab conditions were 25.00 °C, and 747.0 torr barometric pressure. 123.5 mg of Aluminum (MM: 26.98 g/mol) was reacted with 25.00 mL of 1.00 M HCl(ag). 176.68 g of water was collected when the reaction was complete, and it required 15.23 mL of 0.750 M NaOH(aq) to titrate the reaction mixture. Water at 25.00 °C has a density of 0.9970 g/cm3, and a vapor pressure of 23.80 torr. The value for R is 0.082058 L.atm/mol-K What is the ratio of moles H2 gas generated to moles of metal reacting?
