A sealed-tube manometer can be used to measure pressures below atmospheric pressure. The tube above the mercury is evacuated. Wh
en there is a vacuum in the flask, the mercury levels in both arms of the U-tube are equal. If a gaseous sample is introduced into the flask, the mercury levels are different. The difference 'h' is a measure of the pressure of the gas inside the flask. If 'h' is equal to 6.5cm, calculate the pressure in the flask in torr, pascals, and atmospheres. (I need help trying to figure out HOW to get the answer, not what the answer is.)
You are expected to know that a "mill" is one thousandth of a dollar. In this context, it is the amount of tax on one dollar of assessed valuation. So, the tax amount is found by multiplying the valuation by 18.5/1000:
