To determine the density of an irregularly shaped object, a student immersed the object in 21.2 ml
of water in a graduated cylinder causing the level of the water to rise to 27.8 ml. if the object has a
mass of 22.4 grams, what is the density of the object

The density of object is 3.4 g/mL

Explanation:

We are given:

Volume of cylinder without object, = 21.2 mL

Volume of cylinder with object, = 27.8 mL

Volume of object =

To calculate volume of a substance, we use the equation:

We are given:

Mass of object = 22.4 g

Volume of object = 6.6 mL

Putting values in above equation, we get:

Hence, the density of object is 3.4 g/mL

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
