We're being asked to determine the molarity of Zn of an 81% Cu and 19% Zn mixture which has a density of 8760 kg/m3
In this case, follow these steps to determine the molarity of Zn
Step 1. Determine the mass of 1 L of the brass
Step 2. Determine the mass of Zn in this 1 L of brass
Step 3. Convert this mass to moles to calculate for the molarity.
Step 1. In order for us to calculate the molarity, we need to find the mass of 1 L of this brass using density. Recall that molarity can be solved as:
Brass is a substitutional alloy consisting of a solution of copper and zinc. A particular sample of red brass consisting of 81.0% Cu and 19.0% Zn by mass has a density of 8760 kg/m3 .
What is the molarity of Zn in the solution?
