At 25 degrees celsius,one cm3 of iron mass of 7.62 grams. What volume of iron is occupied by 125 grams of iron

density iron=mass/volume=7.62g/cm^3

volume=mass/density=125g/(7.62g/cm^3)

To find the volume of iron occupied by 125 grams, we first need to determine the density of iron. The equation to calculate density is:

Density = Mass / Volume

Since we have the mass and volume of one cm3 of iron at 25 degrees Celsius (7.62 grams), we can use this information to find the density of iron.

Density = 7.62 grams / 1 cm3

Next, we can rearrange the equation to solve for volume:

Volume = Mass / Density

Plugging in the given mass of 125 grams and the density we just calculated, we can calculate the volume of iron occupied by 125 grams.

Volume = 125 grams / (7.62 grams / 1 cm3)

Simplifying the equation gives us:

Volume = 125 cm3 / 7.62

Using a calculator, we get:

Volume ≈ 16.36 cm3

So, 125 grams of iron occupies approximately 16.36 cm3 of volume.
