Answer:

1.Extensive property

2.Intensive property

Explanation:

Matter: It can be anything which occupy space  and has mass.

Example:Wood , stone etc.

Substance:It is a matter .If matter has specific composition and chemical properties .Then , the matter is called substance.

For example: elements such as mercury, sodium etc.

All substance can be matter but all  matter can not be substance.

Substance can be identified by two physical properties:

1.Extensive property

2.Intensive property

1.Extensive property: That property which depend on the amount of substance such as mass, length , volume etc.

Intensive property: That property which does not depend on the amount of substance such as density, boiling point, melting point etc.

By observing these properties we can identify a sample of matter as  substance.

A brick has a mass of 4.0 kg and the Earth has a mass of 6.0 × 1027 g. Use this information to answer the questions below. Be su
Vedmedyk [2.9K]

Answer:

a) 2.4\times 10^{24} kg is the mass of 1 mole of bricks.

b) 2.5\times 10^3 moles of bricks have a mass equal to the mass of the Earth.

Explanation:

a) Mass of brick = 4.0 kg

1 mole = N_A=6.022\times 10^{23} particles/ atoms/molecules

Mass of N_A bricks :

=6.022\times 10^{23}\times 4.0 kg=2.4088\times 10^{24} kg\approx 2.4\times 10^{24} kg

2.4\times 10^{24} kg is the mass of 1 mole of bricks.

b)

Mass of the Earth = M = 6.0\times 10^{27} kg

Mass of 1 mole of brick = m=2.4\times 10^{24} kg

Let the moles of brick with equal mass of the Earth be x.

m\times x=M

x=\frac{M}{m}=\frac{6.0\times 10^{27}kg}{2.4\times 10^{24} kg}=2.5\times 10^3

2.5\times 10^3 moles of bricks have a mass equal to the mass of the Earth.
