A brick has a mass of 4.0kg and the earth has a mass of 6.0*10 to power of 27g
Use this information to answer the questions below be sure your answer have the correct number of significant digits
What is the mass of 1 mole of bricks? In g
How many moles of bricks have a mass equal to the mass of the earth
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 calculate the mass of 1 mole of bricks, we need to know the molar mass of a brick. The molar mass is the mass of one mole of a substance.
However, the information given does not provide the molar mass of the brick. Without this information, we cannot calculate the mass of 1 mole of bricks.
Similarly, we cannot determine the number of moles of bricks that have a mass equal to the mass of the earth because we do not know the molar mass of the brick.
