Determine the percent ammonia, nh3 in co(nh3)6cl3, to three significant figures.

Percent ammonia in   is 38.2 % in 3 significant figures.

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

Molar mass of = 267 g/mol

Mass of =

Thus

Thus percent ammonia in   is 38.2 % in 3 significant figures.

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).
