Gaseous hydrogen has a density of 0.0899g/L at 0 degrees Celsius. How many liters would you need if you wanted 1.0078 g of hydrogen?
Problem- A gaseous mixture contains 436.0 Torr of H2(g), 385.9 Torr of N2(g), and 88.3 Torr of Ar(g). Calculate the mole fraction, X, of each of these gases.
H2 and Cl2 combine to form HCl. In a gas phase equilibrium mixture of H2, Cl2, and HCl at 300 K, [HCl] = 0.0036 mol/L and [Cl2] = 0.00485 mol/L.
The pH of human muscle fluids is 6.8. Calculate the value of H3O+ in muscle fluid at 25 degrees Celcius. The answer should be in scientific notation.
