Montano1993 [528]

According to ideal gas equation, 0.5186 moles of gas are required to occupy 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

<h3>What is ideal gas equation?</h3>

The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.

Substituting the given values in the given equation, n= 5.4×210/8.314×263=0.5186 moles

Thus there are 0.5186 moles occupying  210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.
