What is the composition of gilsonite?

Roughly C100 H140 N3 O

Explanation:

Gilsonite is a bituminous product that resembles shiny black obsidian.

It contains more than 100 elements.

Its mass composition varies but is approximately 84 % C, 10 % H, 3 % N, and 1 % O.

Its empirical formula is roughly C100 H140 N3 O.

3.8 g/mL

Explanation:

From the question given above, the following data were obtained:

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Mass of object = 51.3 g

Density of object =?

Next, we shall determine the volume of the object. This can be obtained as follow:

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Volume of object =?

Volume of object = (Volume of Water + Object) – (Volume of Water)

Volume of object = 73.5 – 60

Volume of object = 13.5 mL

Finally, we shall determine the density of the object as illustrated below:

Volume of object = 13.5 mL

Mass of object = 51.3 g

Density of object =?

Density = mass /volume

Density of object = 51.3 /13.5

Density of object = 3.8 g/mL

Thus, the density of the object is 3.8 g/mL
