Practice Exercise 1Platinum, Pt, is one of the rarest of the metals. Worldwideannual production is only about 130 tons. Platinum has a densityof 21.4 g>cm3. If thieves were to steal platinum from a bank usinga small truck with a maximum payload capacity of 900 lb, howmany 1 L bars of the metal could they take?(a) 19 bars (b) 2 bars (c) 42 bars (d) 1 bar (e) 47 bars
Calculations ( Lab Data is Linked)
1. Determine the number of moles of hydrogen gas that was produced with the complete reaction of the magnesium metal with excess hydrochloric acid.
2. Using Dalton's Law of Partial Pressure and the vapor pressure of water, determine the partial pressure of dry hydrogen gas.
3. Using the ideal gas law based on the collection of dry hydrogen gas, calculate the value of ideal gas law constant, R.
Trial #1:  A piece of magnesium with a mass of 0.330 grams was placed into a solution of hydrochloric acid.  335 mL of hydrogen gas were produce when this reaction occurred at 22.0 °C and a pressure of 747.0 mmHg.
Â
Mg(s) + 2HCl(aq) ⟶⟶ H2(g) + MgCl2(aq)
