A diagram for an open-tube manometer is shown below. (FIGURE CAN'T COPY) If the flask is open to the atmosphere, the mercury levels are equal. For each of the following situations where a gas is contained in the flask, calculate the pressure in the flask in torr, atmospheres, and pascals. (FIGURE CAN'T COPY) c. Calculate the pressures in the flask in parts a and b (in torr) if the atmospheric pressure is 635 torr.
