Question

pressure was measured. Assume that He, being a noble gas, should behave as an ideal gas under typical conditions Moles, n 1.00 1.20 1.40 1.60 1.800 Pressure, P (atm) 28.6 34.4 40.1 45.8 51.5 Without graphing, use your calculator to organize your calculations to determine if there is a constant bias, proportional bias, or random error: determine the error between the measured values and the ideal values, then decide if these are constant, proportional to the ideal pressure, or random. Suggested organization: LI: moles type) L2: measured pressure (type) L3: ideal pressure, based on the moles and the ideal gas law (calculate once LA: the error in the measured pressure: measured pressure ideal pressure (calculate once) L5: the proportion of error to true: error in pressure) adeal pressure) (calculate once) Record theselast values below, rounded to the proper number of significant figures: L4. error L5, proportion of emor

Explanation / Answer

V=1 lit

First we calculate Pideal using ideal gas law PV=nRT

Where P=pressure

n= moles

V=volume=1 lit

R =gas constant=0.082 lit.atm/mol K

T =25 0C =25+273.15=298.15 K
