• (A)Nonmetals, (B)Metals, (C)Metalloids

Unlike nonmetals, most metals tend to-

• conduct heat and electricity well.

• be gases at room temperature.

• break easily when hammered.

• have less luster and shine.

Mass is

• a measure of space

• a measure of amount of matter

• a metric unit of volume

• a comparison of density between materials

Volume is

• a measure of space that matter occupies

• a measure of amount of matter

• the basic metric unit of mass

• a comparison of density between objects

Density is

• anything that has mass and takes up space

• the volume of a substance divided by its mass

• a procedure used to measure volume

• the mass of a substance divided by its volume

Displacement is

• a procedure to measure the volume of a solid by placing it in a known amount of liquid.

• the mass of a substance divided by its volume.

• a metric unit of volume.

• a measure of the space that matter occupies.

Which expression should be used to calculate the density of an object with a mass of 48g and a volume of 6mL

• 48 ÷ 6

• 6 ÷ 48

• 48 - 6

• 6 × 48
