Question

How would you rearrange the ideal gas equation to calculate the pressure of a gas?

• A. Divide nRT by V
• B. Multiply nRT by V
• C. Multiply P by V
• D. Multiply PV by RT
• E. Divide V by nRT

Answer 1

The correct option is A Divide nRT by V

The ideal gas law is the equation of state of a hypothetical ideal gas.

$PV=nRT$

where $P$ is the pressure of the gas,

$V$ is the volume of the gas,

$n$ is the amount of substance of gas (in moles),

$R$ is the ideal, or universal, gas constant, equal to the product of the Boltzmann constant and the Avogadro constant,

$T$ is the absolute temperature of the gas

$\Rightarrow \frac{nRT}{V}$

Divide $nRT$ by $V$
