Chemical elements are pure substances that cannot be broken down into simpler substances by chemical means

WHAT IS A PURE SUBSTANCE:

  • In chemistry, a pure substance is referred to as a substance that contains constant or uniform composition.

  • Chemical elements as pure substances are substances that contain a only one type of atom.

  • All chemical elements are pure substances because they contain only one type of atom in constant proportions. Hence, they cannot be broken down into simpler substances by chemical means.

Therefore, chemical elements are pure substances that cannot be broken down into simpler substances by chemical means.

Answer:

Volume = mass/density

Rearrange the equation for Mass:

Mass = Volume x Density

That is one way you can do it

Conceptually, just look at the units, the wood block's density is 0.6<u>g/cm^3</u> while the volume is 2.2 <u>cm^3</u>

So if density is every gram per centimeter cubed, and the volume is at centimeter cubed, the logical thing to do would be to multiply the density by the volume to get the total mass.

0.6g/cm^3   x   2.2cm^3 = 1.32g

<u>Therefore the mass of the block of wood is 1.32g </u>
