Question

A student uses 0.0821 L• atm/mol • K as the value of the gas constant. What is most likely true about the variables in the ideal gas law?

Answer 1

The Variables in the ideal gas law are taking into account the behave of a gas in ideal conditions. Ideal conditions are established to make all calculations easier than use the real gas equation.

Step-by-step explanation:

If I have 0,082 L*atm/mol*K as ideal constant is because the units and values that I am using are the following:

22.4L, 1mol , 273,15K, 1 atm

Then in the equation: PV=nRT, R=PV/nT = 1atm*22.4L/1mol*273,25K= 0,0821 L• atm/mol • K

Answer 2

The volume of the gas is measured in liters, pressure in pascals, and temperature in degrees Celsius. Option C

The ideal gas law variables are probably measured in liters for volume, pascals for pressure, and degrees Celsius for temperature if a student chooses 0.0821 L⋅atm/(mol⋅K) as the gas constant. The units of the gas constant follow this pattern, where

• The constant is denoted by R.
• P stands for pressure.
• Volume is represented by V.
• n is the mole count, and
• T is the Kelvin temperature.

This decision facilitates the implementation of the ideal gas law in a variety of circumstances by streamlining computations and preserving consistency.

What is most likely true about the variables in the ideal gas law if a student uses 0.0821 L⋅atm/(mol⋅K) as the value of the gas constant?

A. The volume of the gas is measured in liters, pressure in atmospheres, and temperature in kelvins.

B. The volume of the gas is measured in milliliters, pressure in pascals, and temperature in degrees Celsius.

C. The volume of the gas is measured in liters, pressure in pascals, and temperature in degrees Celsius.

D. The volume of the gas is measured in milliliters, pressure in atmospheres, and temperature in kelvins.
