I'm not sure, but i think it is around 0.76g/cc, based on this:
leather density measure:
The vast majority of leather is sold according to its area. The leather is placed through pin-wheel or electronic measuring machines and its surface area is determined. The unit of measurement is square meter, square decimeter or square foot. The thickness is also important, and this is measured using a thickness gauge (the unit of measurement is millimeters, e.g., 1.8 mm is a standard thickness for a school shoe).
In some parts of the world, top-grain thicknesses are described using weight units of ounces. Although the statement is in ounces only, it is an abbreviation of ounces per square foot. The thickness value can be obtained by the conversion: 1 oz/ft² = 1/64 inch (0.4 mm).
Hence, leather described as 7 to 8 oz is 7/64 to 8/64 inches (2.8 to 3.2 mm) thick. The weight is usually given as a range because the inherent variability of the material makes ensuring a precise thickness very difficult. Other leather manufacturers state the thickness directly in millimeters.
7 ounces = 198.446662 grams
8 ounces = 226.796185 grams
it is an abbreviation of ounces per square foot:
1 (square foot) = 929.0304 square centimetres
1 (square foot) = 92 903.04 square millimetres
92 903.04mm^2 * 3.2mm = 297 289.728mm^3
226g / 297 289.728mm^3 =
226g / 297.289728cc = 0.760201173g/cc

Why things made up of leather float on water?
Leather floats on water due to its density being lower than that of water. The pores in leather create air pockets that help increase buoyancy, allowing it to float. Additionally, the natural oils and other substances present in leather can repel water, further contributing to its buoyancy.
Is leather ductile?
Yes, leather is ductile. It is known for its flexibility and ability to be molded into different shapes without breaking. However, the level of ductility in leather can vary depending on the type and quality of the leather.
What is the refractive index of leather?
The refractive index of leather can vary depending on the type and processing of the leather. However, in general, the refractive index of leather falls in the range of 1.40 to 1.55.
Is leather magnetic?
No, leather is not magnetic. Magnetic materials are those that are attracted to a magnet or can be magnetized, which does not apply to leather since it is not a magnetic material.
Is leather opaque?
Yes, leather is opaque. It is a thick material that does not allow light to pass through it. This is due to the dense fibers and tanning process used to create leather.
