The following data is collected after eluting a tlc plate containing three sample spots (a, b, and c): distance traveled by compound a = 32 mm, distance traveled by compound b = 48 mm, distance traveled by compound c = 18 mm, distance traveled by solvent front = 64 mm and length of the tlc plate = 70 mm. what is the rf value of compound c? enter your answer using the proper number of significant figures.

Rf = 0.26

Explanation:

The Rf value is calculated by dividing the distance traveled by a compound, by the distance traveled by the solvent front. In other words, the length of the TLC plate is not relevant in calculating a Rf value.

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).
