MOLAR ELEMENT SET (MOLE): 4x Metals | Useful for scientific application

$ 25.50 excl. GST

MOLAR ELEMENT SET

This Mole Set helps students visualise a mole in solid state. It comprises four metal element samples: copper, iron, zinc and aluminium; each contains one mole, 6.02 x 1023 atoms of the element. This will help students develop a greater understanding of the concept of the mole, mass, molar mass as well as a greater knowledge of the properties of each element when these specimens are compared side-by-side.

(Wikipedia excerpt: …”…In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles.[1] The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes. Most commonly, the molar mass is computed from the standard atomic weights and is thus a terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth.

The molar mass is appropriate for converting between the mass of a substance and the amount of a substance for bulk quantities…The molecular weight is commonly used as a synonym of molar mass, particularly for molecular compounds; however, the most authoritative sources define it differently (see Molecular mass).The formula weight is a synonym of molar mass that is frequently used for non-molecular compounds, such as ionic salts…”…)
