Problem

A sealed container holds

2.10\times10^{23}

molecules of an ideal gas at a temperature of

295\,\text{K}

and a pressure of

1.30\times10^{5}\,\text{Pa}

. The gas occupies

6.50\times10^{-3}\,\text{m}^3

. Using these data, what experimental value of the universal gas constant is obtained? (a)

9.6\,\text{J\,mol}^{-1}\,\text{K}^{-1}

(b)

7.1\,\text{J\,mol}^{-1}\,\text{K}^{-1}

(c)

8.3\,\text{J\,mol}^{-1}\,\text{K}^{-1}

(d)

11\,\text{J\,mol}^{-1}\,\text{K}^{-1}
