A 1.50 g piece of substance 8.52g was rolled out into a thin sheet measuring 24.0cm × 30.0cm

The volume of the sheet metal = 0.58 cm³

Note: The question is incomplete. A similar complete question is given below:

a 7.50 g piece of metal was rolled into a thin sheet measuring 24.0 cm × 30.0 cm

the density of the metal is 12.86 g/cm

calculate the volume of the sheet of metal

Explanation:

The mass of a substance is the quantity of matter present in that substance

The volume of a substance is amount of space the substance occupies

Density of a substance is the ratio of its mass and the volume it occupies. It is a measure of how compact a body is.

From definition above;

Density = mass/volume

Therefore, volume = mass/density

mass of thin sheet = 7.50 g

density = 12.86 g/cm³

Volume = 7.50 g / 12.86 gcm⁻³

Volume = 0.58 cm³

Therefore, the volume of the sheet metal = 0.58 cm³
