Question

The pressure of a gas is measured as 49 torr. Represents this pressure in both atmospheres and pascals.​

Answer 1

Answer:

The manometer—a device for measuring the pressure of a gas in a container. The pressure of the gas is given by h [the difference in mercury levels] in units of torr (equivalent to mm Hg). The pressure of a gas is measured as 49 torr. Represent this pressure in both atmospheres and Pascals.

Key Points

2)The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+… ...

1)The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.

Gases exert pressure, which is force per unit area. The pressure of a gas may be expressed in the SI unit of pascal or kilopascal, as well as in many other units including torr, atmosphere, and bar.
