A block of iron has a mass of 483 g. What is the mass of a block of graphite that has the same volume as the block of iron The following densities at 25^$\circ$C are provided: agnesium, 1.7 g/cm³ ; graphite, 1.8 g/cm³ ; iron, 7.9 g/cm³. A) 110 g B) 2120 g C) 6870 g D) 34 g E) none of them are within 10 g of the right answer.

The mass of the graphite block can be calculated using the formula:mass = density * volumeThe volume of the graphite block is the same as the volume of the iron block, so we can use the density of iron to calculate the volume:volume = mass / densityvolume = 483 g / 7.9 g/cm³volume = 61.1 cm³Now we can use the density of graphite to calculate the mass of the graphite block:mass = density * volumemass = 1.8 g/cm³ * 61.1 cm³mass = 110 gTherefore, the mass of the graphite block is 110 g.
