The density of iron at 25 C is 7.871 g/cm^3
what is the volume of one mole of solid iron at 25 C?
i understand that volume = m/d but how would i go about solving this?
To find the volume of one mole of solid iron at 25°C, you need to have the mass of one mole of iron and the density of iron at that temperature.
Here's how you can solve it:
1. Start with the given density of iron at 25°C: 7.871 g/cm^3.
2. Determine the molar mass of iron. The molar mass of iron is the mass of one mole of iron atoms. The molar mass of iron is approximately 55.85 g/mol.
3. Use the molar mass to find the mass of one mole of iron. This can be done by multiplying the molar mass by the number of moles, which is 1. So, the mass of one mole of iron is 55.85 g/mol.
4. Now you have the mass (55.85 g/mol) and the density (7.871 g/cm^3) of iron, which are needed to find the volume.
5. Rearrange the formula for density to solve for volume: volume = mass / density.
6. Substitute the calculated values into the formula: volume = 55.85 g/mol / 7.871 g/cm^3.
7. Calculate the volume: divide the mass (55.85 g/mol) by the density (7.871 g/cm^3) to get the volume.
The resulting volume will be in cubic centimeters (cm^3) since the density was in grams per cubic centimeter (g/cm^3).
