#m = overbrace((PV)/(RT))^(color(blue)('the number of moles')) * M_M#įinally, plug in your values to find the mass of the sample-do not forget to convert the temperature from degrees Celsius to Kelvin and the pressure from mmHg to atmospheres! This means that you can rewrite the ideal gas law equation as You also know that the mass of the gas, let's say #m#, can be expressed in terms of its molar mass, let's say #M_M#, and the number of moles. For 746 kilopascal, the best unit to convert to is 746 kilopascal. #T# is the absolute temperature of the gas Best conversion unit for 746 kilopascal The best conversion unit defined in our website is to convert a number as the unit that is the lowest without going lower than 1.#R# is the universal gas constant, equal to #0.0821('atm L')/('mol K')# Perform each of the following unit conversions using the conversion factors given below:1 atm 760 mmHg 101.325 kPa (Round answer to 4 significant figures.#n# is the number of moles of gas present in the sample.#color(blue)(ul(color(black)(PV = nRT)))# Standard atmospheric pressure of 1013.25 mb at 0 m, 226.321 mb at 11,000 m, 54.7489 mb at 20,000 m above mean sea level. So, you know that the ideal gas law equation looks like this The height relative to sea level conversions are derived using the US Standard Atmosphere 1976 barometric formula for geopotential altitude with the following values1-6 at heights from 5,000 ft (1524 m) below to 100,000 ft (30,480 m) above mean sea level. You could also rewrite the ideal gas law equation in terms of the mass of helium present in the sample to get the answer directly. If the volume of the gas is increased to 9.0 L, what will the pressure beExpress your answer using two significant figures. The idea here is that you can use the ideal gas law equation to find the number of moles of helium present in your sample and the molar mass of the gas to convert that to grams. 1 Inch Of Water to common pressure units 1 inH2o 248.843 pascals (Pa) 1 inH2o 0.0024558894645941 atmosphere atm standard (atm) 1 inH2o 1.8664811508978 millimeter of mercury (mmHg) 1 inH2o 0.00248843 bars (bar) 1 inH2o 1.8664759931063 torrs (Torr) 1 inH2o 3.6091625769833E-5 ksi (ksi) 1 inH2o 0.
