A 0.530 m aqueous solution of KBr has a total mass of 61.0 g. What masses of solute and solvent are present? g

Explanation:

Hello,

In this case, since the given concentration is molality, we have:

Whereas the mass of the solvent (water for aqueous solution) is given in kg. Moreover, since the total mass of the solution is 61.0 g, one could write:

Which is replaced in the definition of molality:

Thus, solving for the mass of solution we obtain:

Therefore, the mass of the solvent is:

Best regards.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
