Find the density of a material given when a 5.03 g sample is place in 47.54 ml of water the water level rises to 50.78 ml

The density of a material given is 1.55 g/mL

Explanation:

Density = Mass per unit volume of the substance .

Initial Volume of water = 47.54 mL

Total volume = Volume of water + material = 50.78 mL

Volume of material = Total volume - volume of water

Volume of material = 50.78 - 47.54 = 3.24 mL

Volume of material = 3.24 mL

Mass of the material = 5.03 g

The density of a material given is 1.55 g/mL

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.
