Answer:

7.92gml-1

Explanation:

water=25.20ml

water+iron=25.92ml

iron=5.7g

P=mass/volume (formula of density)

mass=5.7g

volume=25.92-25.20

=0.72ml

p=5.7/0.72

=7.92gml-1

Given:

Initial volume of water = 25.20mL

Volume of water after iron is added = 25.92mL

Mass of iron = 5.7g

So, the volume of iron = 25.92mL - 25.20mL = 0.72mL

∴ Density of iron will be

Density = Mass/Volume

Density = 5.7g / 0.72mL

Density = 7.91 g/mL

What is density in short answer?

The density of a substance is the relationship between its mass and how much space it takes up. Density equals the mass of the substance divided by its volume, D = m/v.

What is the SI unit of density?

Though SI unit of density is kg/m³ solids, g/ml for liquids and g/L for gases.
