Problem

At a mountain research station the atmospheric pressure is measured to be

8.4 \times 10^4\,\text{Pa}

. A container kept there has an internal gauge pressure of

15\,\text{kPa}

.\ Calculate the absolute pressure inside the container and express your answer in millimetres of mercury (mm Hg).\ Take density of mercury

\rho_{\mathrm{Hg}} = 13.6 \times 10^3\,\text{kg\,m}^{-3}

and

g = 9.8\,\text{m\,s}^{-2}
