5 & 6 go together. 

In questions 5 and 6, assume 1.00 mol of any gas occupies 22.40 L at standard temperature and pressure (STP). 5. What volume of hydrogen gas is obtained when 9.62 g of chromium metal reacts with an excess of dilute sulfuric acid at STP? 2 Crs) + 3 H2SO4 (aq) → Cr2(SO4)3 (aq) + 3 H2 (g) 6. What volume of oxygen, at STP, is required to burn exactly 1.58 L of methane (CH4 (9), according to the reaction below? CH4 (9) + 202 (9) CO2 (9) + 2H2O (G) (6) 7. How much faster does N2 gas escape through a porous container than Kr? 8. Calculate the pressure inside a tube, given that the tube's volume is 4.0 L, its temperature is 22 °C, and it contains 1.57 mg of hydrogen gas.
