SI unit of pressure and units of pressure commonly used in the United States are to be stated. The reason as to why these common units are more convenient to use than the SI unit is to be stated. Manometer is to be described and how this can be used to measure the pressure of gas sample is to be explained. Concept Introduction: SI units can be defined as the international standard units used widely in the world. Manometer is used to measure pressure. It consists of a U shaped gas tube filled with an appropriate liquid. Generally the liquid used in manometer is mercury.

Question

[References] A steel cylinder contains 5.00 moles graphite (pure carbon) and 5.00 moles O2. The mixture is ignited and all the graphite reacts. Combustion produces a mixture of CO gas and CO2 gas. After the cylinder has cooled to its original temperature, it is found that the pressure of the cylinder has increased by 40.0%. Calculate the mole fractions of CO, CO2, and O2 in the final gaseous mixture. Mole fraction of CO = Mole fraction of CO2 Mole fraction of O2 = Submit Answer Try Another Version 3 item attempts remaining Visited

Potassium chlorate, potassium chloride, and water is produced by passing chlorine gas into a hot solution of potassium hydroxide. Calculate the volume in L of chlorine gas needed to produce 724.25 mL of 4.25 M potassium chlorate. The density of chlorine gas is 3.17 g/L. Atomic Mass: K: 39.098 g/mol Cl: 35.453 g/mol O: 15.999 g/mol H: 1.008 g/mol
