In ideal gas equation calculations, expressing pressure in Pascals (Pa), necessitates the use of the gas constant, R, equal to 1 Select one: a. 0.08206 atm L mol b. 8.314 m-Pa/mol-K c. 62.36 L torr mollk-1 d. 1.987 cal mol K-1 e. None of these
Simple gas laws What is the effect of the following changes on the volume of 1 mol of an ideal gas? (Note: You should NOT need to do any explicit numerical calculations. Use your qualitative understanding of how volume depends on different experimental variables.) The pressure is changed from 2 atm to 760 torr (at constant temperature). (1, 1/2, 1/4,2) Half the gas escapes through a stopcock (at constant temperature and pressure). Answer 2 Both the pressure and the temperature...
Taking into account the vapor pressure of water, how many moles of hydrogen gas, n, are present in 343 mL at 752 torr and 29 ∘C?The value of the gas constant R is 0.08206 L⋅atm/(mol⋅K). You may also find the conversion factors 1 atm=760 torr and TK=TC+273 useful. Express the number of moles to three significant figures.
QUESTION 3 A student collected a sample of hydrogen gas in a eudiometer over a water bath to experimentally determine the value of the gas constant, R. Calculate the experimental value of Rif the pressure of the gas was 0.991 atm, the volume was 36.3 mL the temperature was 292 K and the sample contained 1.54 x 103 moles of gas.
