Caculate the mass of a solid with a density of 14.2 g/cm cubed and a volume of 350 cm cubed​
shepuryov [24]

Answer:

The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.

Explanation:

Formula for density is given below :

density = \frac{mass}{volume}

volume = 350 cm^{3}

density = 14.2 g/cm^{3}

Insert the values in the formula

14.2 = \frac{mass}{350}

on cross multiplication :

mass = density\times volume

mass = 14.2\times 350

mass = 4970 g

1 g = 0.001 Kg

mass =4970\times 0.001 Kg

mass = 4.97 Kg

Note : Check the units of volume and density carefully

Alexus [3.1K]

Answer:

The mass of the lead

Explanation:

The 5g mass of the lead is an extensive property.

An extensive property is a physical property of matter which depends on the amount of matter that is present there in. Mass, volume e.t.c are all extensive properties. The more the quantity of the lead, the more its mass and the volume it occupies.

Melting point, boiling point, density are all intensive propeties. These properties do not rely on the amount of matter present. Any amount of lead will have the same density.
