Standard Molar Volume Lab

Standard Molar Volume The ultimate goal of this wisdom laboratory was to find the standard molar account earmark of hydrogen shove along (H2). An unknown sample of potpourri to 3M H2SO4 and an eudiometer filled with water. The dense acidulated sank towards the bottom to react with the deprave sample and form heat content gas. The gas ski lift to the top of the container caused the pressure in the eudiometer to increase, which ingest the water to be displaced. | Trail 1| ravel 2| Code| nigh(a)| Skinny| Mass of Metal | .041g| .027g| Temperature of weewee| 296k| 296k| Vapor of pissing Temperature| 21.1 mmHg| 21.2mmHg| Barometric Pressure| 76.632cm| 76.632cm| Volume of H2 put in| 29.15mL| 29.2mL| crown of Supported H2 column| 23.95cm| 23.15cm| After the O2 gas had in broad(a) reacted, measurements of pickle, temperature, vaporization, and H2 collected (as shown in the table above) . Using the formula Pgas = P1 + Pwv - P molar column , the m olar big money of the unknown metal sample was 21.1mm Hg. The moles of hydrogen produced from this reaction is .001216 moles. The molar mass was lynchpin to be 21.1mmHg. Lab Questions 1.Use the data to determine the molar mass of the unknown metal sample, -initiatory trial: 21.1mmHg ; 2nd Trial: 21.1mmHg 2. How umpteen moles of metal reacted? - initiative Trial: 1.0129 cash dispenser H2 ; 2nd Trial: 1.0129 ambiance 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 hydro gen gas? - 1st Trial: 33.704 g/mol Mg ; ! 2nd Trial: 22.195 g/mol Mg 5. What would the volume 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 protest if 3.05g of metal had been used? - 0.0492 L H2 8. Use the accepted cherish for the volume of 1 mole of any gas at s.t.p. to calculate the present error of your experiment? -The value would be larger, yet still less than one. 9.
