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.
