The catalyst has been represented with the formula above the arrow in the chemical equation.
The catalyst has been the compound or element in the chemical reaction that helps in the lowering of the activation energy of the system and thereby leads to an increase in the rate of the reaction.
The chemical equation has been represented in the form of the chemical formula of the reactants and the products.
The catalyst has not been consumed in the chemical reaction, thus it has been represented with the formula above the arrow in the chemical equation.

Answer:
3.8 g/mL
Explanation:
From the question given above, the following data were obtained:
Volume of Water = 60 mL
Volume of Water + Object = 73.5 mL
Mass of object = 51.3 g
Density of object =?
Next, we shall determine the volume of the object. This can be obtained as follow:
Volume of Water = 60 mL
Volume of Water + Object = 73.5 mL
Volume of object =?
Volume of object = (Volume of Water + Object) – (Volume of Water)
Volume of object = 73.5 – 60
Volume of object = 13.5 mL
Finally, we shall determine the density of the object as illustrated below:
Volume of object = 13.5 mL
Mass of object = 51.3 g
Density of object =?
Density = mass /volume
Density of object = 51.3 /13.5
Density of object = 3.8 g/mL
Thus, the density of the object is 3.8 g/mL
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.
John Dalton
"matter cannot be created nor destroyed or divided into smaller particles"
