How do i calculate the mass in grams for this problem?

Hey there!:

Mass = ?

Density = 0.713 g/mL

Volume = 21.9 mL

Therefore:

D = m / V

0.713 = m / 21.9

m = 0.713 * 21.9

m = 15.6147 g

the answer would be b i believe

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).
