C. Molecule is a pure substance. It may be 2 or more atoms binding together via covalent bonding (I.e. the sharing of electrons). The bonding of two or more atoms from the same element forms stable molecules.
The bonding of two different atoms or more will result in a completely new substance as compared to the original substances of atoms.

Mixtures, from the name itself, are being mixed with several solutions, where one part of it is soluble, and the other part is insoluble.
●For e.g., sand and seawater being put together forms a mixture, where sea water is water and salt (soluble together) and sand (insoluble with water and salt).

Solutions may be 2 or more substances being mixed together which are soluble.
● For the sea water example above, sea water is the solution, since salt can be desolved in water (i.e. the solute).

Hope this helps! :)

Iodine is 80% 127I, 17% 126I, and 3% 128I. Calculate the average atomic mass of Iodine.
trasher [3.6K]
<h3>The average atomic mass of Iodine : 126.86 amu</h3><h3>Further explanation</h3>

Given

80% 127I, 17% 126I, and 3% 128I.

Required

The average atomic mass

Solution

The elements in nature have several types of isotopes

Atomic mass is the average atomic mass of all its isotopes

Mass atom X = mass isotope 1 . % + mass isotope 2.% + ... mass isotope n.%

Atomic mass of Iodine = 0.8 x 127 + 0.17 x 126 + 0.03 x 128

Atomic mass of Iodine = 101.6 + 21.42 + 3.84

Atomic mass of Iodine = 126.86 amu
