What pressure (in atm) is exerted by a column of mercury 1.10 m high? The density of mercury is 13.5951 g/cm3.

1 Atm supports a column of mercury 760 mm high, so, A column of 1.10 m = 1100 mm => P = 1100 mm/760 mm/Atm = 1.5 Atm (2 Sig. Figs)
A sample consisting of 1.00 mol Ar is expanded isothermally at 0°C from 22.4 dm3 to 44.8 dm3 (a) reversibly, (b) against a constant external pressure equal to the final pressure of the gas, and (c) freely (against zero external pressure). For the three
