Question

The element bromine at room temperature is a liquid with a density of 3.12 g/ml. Calculate the mass of 125ml of bromine. What volume does 85.0g of bromine occupy?

Answer 1

To calculate the mass of 125 ml of bromine with a density of 3.12 g/ml, the formula Mass = Density × Volume gives us 390 g. To find the volume that 85.0 g of bromine occupies, the formula Volume = Mass / Density results in approximately 27.24 ml.

Step-by-step explanation:

The mass of a substance can be calculated using its density and the volume it occupies. The formula for mass is density multiplied by volume: Mass = Density × Volume. With a density of 3.12 g/ml for bromine, the mass of 125 ml of bromine can be calculated as follows:

Mass = Density × VolumeMass = 3.12 g/ml × 125 mlMass = 390 g

To find the volume that 85.0 g of bromine occupies, we can rearrange the formula to: Volume = Mass / Density. Therefore:

Volume = Mass / DensityVolume = 85.0 g / 3.12 g/mlVolume ≈ 27.24 ml

Thus, 125 ml of bromine has a mass of 390 g, and 85.0 g of bromine would occupy approximately 27.24 ml.
