A student perfоrms the lаb оn аn unknоwn metаl and obtains the following data: Measurement Result Mass of metal (g) 0.0285 g Temperature of laboratory (°C) 21°C Volume of H2 gas produced (mL) 26.5 mL Gas Constant R 0.08206 (L atm)/(mol K) Pressure in Laboratory (atm) P 0.975 atm Using this data, complete the following calculations: Molar ratio of H:M assuming a 1:1 ratio of M to H2. We will assume a 1:1 molar ratio for this experiment. Moles of metal used: ________________
