For an ideal gas, it is equal to the ratio of the product of molar mass and pressure to the gas constant times temperature.
This value for a substance can be obtained using the Baumé scale or a hydrometer. For an ideal gas, it is equal to the ratio of the product of molar mass and pressure to the gas constant times temperature. It is symbolized by rho. Among the natural elements, (*) osmium and iridium have the highest value of this. Though this quantity typically increases upon freezing, its decrease when water freezes explains why ice floats. For 10 points, name this ratio of mass to volume, which, for water, is about one gram per milliliter.
