One litre of acetone can dissolve around 250 litres of acetylene at a pressure of 10 bars (1.0 MPa). [62] [63] Acetone is used as a solvent by the pharmaceutical industry and as a denaturant in denatured alcohol. [64] Acetone is also present as an excipient in some pharmaceutical drugs. [65] [needs update]
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...

It only has three cylinders, while four cylinders are much more common for vehicles of this size and its 26-mpg (miles per gallon) gas mileage is on the lower end for a midsize SUV.

Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
