a researcher plots pressure

P

on the y-axis versus the reciprocal of volume

1/V

on the x-axis for a sample of ideal gas. The resulting straight line has a slope of

7.5\times10^{3}\,\text{Pa}\cdot\text{m}^{3}

. Approximately how many moles of gas are in the sample? (a)

0.30\,\text{mol}

(b)

30\,\text{mol}

(c)

3.0\,\text{mol}

(d)

0.03\,\text{mol}
