Apiece of a metal that has a density of 5.2g/cm3 and a mass of 100g was placed in a full jar of water. how many ml of water spilled out of the jar. note one cm3=one ml

19.23mL

Explanation:

Data

Density of the metal (ρ) = 5.2g/cm³

Mass of the metal (m) = 100g

Volume of water spilled (v) =?

The volume of water spilled would be equivalent to the volume of the metal since the metal would occupy that same volume in the jar.

Density = mass / volume

ρ = m / v

v = m / ρ

v = 100 / 5.2

v = 19.23 mL

Therefore the volume of water spilled is 19.24mL

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
