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

Answer:

- the pressure is specified in atmospheres (atm)

- the volume is specificied in liters (L)

- the temperature is specificied in Kelvin (K)

- the number of moles is specified in mol (mol)

Explanation:

The ideal gas law states that:

$pV=nRT$

where

p is the gas pressure

V is the volume

n is the number of moles

R is the gas constant

T is the absolute temperature

It can be rewritten solving for R

$R=\frac{pV}{nT}$

In this problem, the gas constant is written as

$R=0.0821 \frac{L \cdot atm}{mol\cdot K}$

this means that:

- the pressure is specified in atmospheres (atm)

- the volume is specificied in liters (L)

- the temperature is specificied in Kelvin (K)

- the number of moles is specified in mol (mol)
