The ideal gas equation is

  • A. PV equals nRT
  • B. PV equals nR divided by T
  • C. P divided by V equals nRT
  • D. PVT equals nR

Explanation

The equation combines Boyle's, Charles's and Avogadro's laws into one relation, with R the universal gas constant at 8.314 J per mole per kelvin. Every quantity must be in consistent units, and the temperature must always be absolute. Rearranging it gives the density and molar mass of a gas from measurable quantities.
