To find the mass of 1 mole of bricks, we need to know the molar mass of bricks. Without that information, we cannot accurately determine the mass of 1 mole of bricks.
To find the number of moles of bricks that have a mass equal to the mass of the earth, we can use the following equation:
Moles of bricks = Mass of the earth / Mass of 1 brick
Given that the mass of the earth is 6.0 * 10^27 g and the mass of 1 brick is 4.0 kg, we need to convert the units to the same base:
Mass of the earth = 6.0 * 10^27 g = 6.0 * 10^30 mg (since 1 g = 1000 mg)
Mass of 1 brick = 4.0 kg = 4.0 * 10^6 g (since 1 kg = 1000 g)
Now we can calculate the number of moles of bricks:
Moles of bricks = 6.0 * 10^30 mg / 4.0 * 10^6 g
Dividing the two values, we find:
Moles of bricks ≈ 1.5 * 10^24 moles
Therefore, there are approximately 1.5 * 10^24 moles of bricks that have a mass equal to the mass of the earth.
To find the number of moles of bricks that have a mass equal to the mass of the earth, we can use the following equation:
Moles of bricks = Mass of the earth / Mass of 1 brick
Given that the mass of the earth is 6.0 * 10^27 g and the mass of 1 brick is 4.0 kg, we need to convert the units to the same base:
Mass of the earth = 6.0 * 10^27 g = 6.0 * 10^30 mg (since 1 g = 1000 mg)
Mass of 1 brick = 4.0 kg = 4.0 * 10^6 g (since 1 kg = 1000 g)
Now we can calculate the number of moles of bricks:
Moles of bricks = 6.0 * 10^30 mg / 4.0 * 10^6 g
Dividing the two values, we find:
Moles of bricks ≈ 1.5 * 10^24 moles
Therefore, there are approximately 1.5 * 10^24 moles of bricks that have a mass equal to the mass of the earth.
