Determination of value of R Calculations (You must show your method of solution) (1) Calculated value for R 685090 Use the observed volume of oxygen and the appropriate values and units for number of moles, pressure and temperature. co.946an 0.255612) -0.2417 70.012 Soad) (294k) 3.528 255.0 - leto (2) Absolute error in R value (3) Percent error in R value

Answer 1

di calculate value for R. From ideal gas law R=PV I atm 22.4L mol 2734 -0.08 205 Latm MOLK. when p = 101325 Nim N=0.09. 24 m3 thens N 0.0224 m R = 10132.5 1 mol 273K = 8.314] Imolika

(1) one mole of gas at STP = 22.4 Lf mol. molar moss of O2 = 32 g/mol. Density = mass volume = 329/mole 22.4Li mole => 1.428 = 4.439 / L.
