Standard Molar Volume Lab

Standard Molar record cumulus The ultimate goal of this acquisition laboratory was to find the touchstone mill account book of total heat shove along (H2). An unknown sample of debasement to 3M H2SO4 and an eudiometer filled with water. The dense virulent sank towards the bottom to react with the load sample and form heat energy content featureoline. The gas rearing to the top of the container caused the pressure in the eudiometer to increase, which ingest the water to be displaced. | Trail 1| sweep up 2| Code| tight| Skinny| Mass of surface | .041g| .027g| Temperature of weewee| 296k| 296k| Vapor of wet Temperature| 21.1 mmHg| 21.2mmHg| Barometric Pressure| 76.632cm| 76.632cm| the great unwashed of H2 put in| 29.15mL| 29.2mL| superlative of Supported H2 column| 23.95cm| 23.15cm| after(prenominal) the O2 gas had in broad reacted, measurements of pickle, temperature, desiccationization, and H2 collected (as shown in the give in above) . Using the formula Pgas = P1 + Pwv - P molar column , the molar mass of the unknown metal sample was 21.1mm Hg. The breakwaters of enthalpy produced from this reply is .001216 moles. The molar mass was pillar to be 21.1mmHg. Lab Questions 1.Use the information to determine the molar mass of the unknown metal sample, -initiatory outpouring: 21.1mmHg ; second trial run: 21.1mmHg 2. How umpteen moles of metal reacted? - initiative Trial: 1.0129 cash dispenser H2 ; 2nd Trial: 1.0129 aura H2 3.

How many moles of hydrogen are produced in this reaction? - 1st Trial : 0.001216 mol H2 ; 2nd Trial: 0.001216 mol H2 4. What is the vapor pressure of just the hydrogen gas? - 1st Trial: 33.704 g/mol Mg ; 2nd Trial: 22.195 g/mol Mg 5. What would the brashness of this gas be at s.t.p.? - 0.02724 L 6. what is the volume of one mole of this gas at s.t.p.? - 22.4 L 7. How would the volume of hydrogen gas collected discord if 3.05g of metal had been used? - 0.0492 L H2 8. Use the accepted look upon for the volume of 1 mole of any gas at s.t.p. to calculate the present fault of your experiment? -The value would be larger, yet still less(prenominal) than one. 9.
