what is the mass of 1 mole of bricks?
how many moles of bricks have a mass equal to the mass of the earth? write answer as a decimal to one decimal place.

Mass of 1 mole of brick is kg. 2500 moles of brick will weigh the same as the mass of the earth.

(a) Mass of 1 mole of bricks:

Mass of 1 mole = weight Avagadro number

Mass of 1 mole brick = 4.0

Mass of 1 mole of brick is kg.

(b) Number of moles of bricks having mass equal to earth:

=

=

= 2.5 moles

= 2500 moles of brick will weigh the same as the mass of the earth.

To have the mass equal to that of earth, the required number of moles of bricks are .

Given data:

The mass of brick is, m = 4.0 kg.

The mass of Earth is, .

Number of moles of brick is, n = 1.

(a)

The mass of 1 mole of bricks is,

Thus, the mass of 1 mole of bricks is  .

(b)

The number of moles (N) of brick to have mass equal to the mass of the earth is expressed as,

Thus, for having the mass equal to the mass of the earth, the brick should have number of moles.
