What is the pressure of the gas inside the apparatus in mm Hg if the outside pressure is 0.975 atm?

CONCEPTUAL PRACTICE 10.3 What is the pressure of the gas inside the apparatus in mm Hg if the outside pressure is 0.975 atm? Gas CONCEPTUAL APPLY 10.4 Assume that you are using an open-end manometer filled with mineral oil rather than mercury. The level of mineral oil in the arm connected to the bulb is 237 mm higher than the level in the arm connected to the atmosphere and atmospheric pressure is 746 mm Hg. (a) Draw a picture of the manometer similar to Figure 10.5. (b) What is the gas pressure in the bulb in mm of Hg? (The density of mercury is 13.6 g/mL, and the density of mineral oil is 0.822 g/mL.) 24.7 cm 10.2 THE GAS LAWS Unlike solids and liquids, different gases show remarkably similar physical behavior regardless of their chemical makeup. Helium and fluorine, for example, are vastly differ- ent in their chemical properties yet are almost identical in much of their physical behavior. Numerous observations made in the late 1600s showed that the properties of any gas can be defined by four variables: pressure (P), temperature (T), volume (V), and amount, or number of moles (n). The specific relationships among these four variables are called the gas laws and a gas whose behavior follows the laws exactly is called an ideal gas Open-end manometer for Problem 10.3
