Problem

A student plots pressure versus temperature for a fixed volume of gas and obtains a best-fit slope of

m=420\,\text{Pa}\,\text{K}^{-1}

. The gas occupies a constant volume of

V=400\,\text{mL}

and contains

n=0.020\,\text{mol}

. Using the slope, determine a value for the universal gas constant

R

\text{J}\,(\text{mol}\cdot\text{K})
