(Q31) Given that a sample of krypton gas effuses in 18.4 minutes, how long (in minutes) will it take an equal volume of oxygen gas in the same apparatus at the same temperature and pressure to effuse? (Report to one decimal place)

Molecular weight of a volatile liquid A student had the following data:mass of volatile liquid: 0.317 gpressure: 1.076 atmtemperature C: 97.8volume of flask: 130.8 mLThe student calculated the molar mass to be 0.06857 g / mol which is impossible since H has a molar mass of 1.008 g / mol! The error that the student made was ... A) Not converting Celsius to Kelvin B) No errors were made.   C) This unusual compound does have a fractional molar mass less than one and is the only known compound with such a mass. D) Not converting the volume from mL to L E) Using the wrong gas constant

A given mass of a gas at 52 celcius has a pressure of 3.6 *104 Nm-2and occupies a volume of 1.8 dm3. what will be its new volume if its pressure is increased to 4.8*104Nm-2 at the same temprature

Part B The pressure in car tires is often measured in pounds per square inch (Ib/in.), with the recommended pressure being in the range of 25 to 45 lb/in.2. Suppose a tire has a pressure of 42.5 lb/in.? . Convert 42.5 lb/in.? to its equivalent in atmospheres. Express the pressure numerically in atmospheres. • View Available Hint(s) να ΑΣφ ? 42.5 lb/in.? : atm
