5) Select True or False. If False, select the statement that makes it True. A piece of plastic is not a mineral because it is made in a factory and is not found naturally in the Earth. True False; A piece of plastic is a mineral because it is inorganic. False; A piece of plastic is a mineral because it is made in a factory and is not found naturally in the Earth False; A piece of plastic is a mineral because it is a mixture.​

b is correct

Explanation:

plz mark me brainliest

True

Explanation:

The answer is true because Plastic is not a mineral. It is a solid and it has a definite chemical composition. Plastic is made from oil (an organic material) and it is made by humans - plastic is not a naturally occurring substance.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
