How much mass do 2.6 moles of gold contain

512.114 g

We are given;

we are required to calculate the mass of gold

Mass = Moles × molar mass

In this case;

Mass of Gold = 2.6 moles × 196.967 g/mol

                      = 512.1142 g

                      = 512.114 g

Thus, the mass of gold is 512.114 g

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
