Answer:
See explanation below
Step-by-step explanation:
You are missing two values there. First, we need to know the concentration or initial quantity of the silver perchlorate solution, and then, the quantity in grams or moles of the solution.
Tipically these kind of questions, usually gives the original concentration of the solution, and then, the grams or moles.
In this case, you are not providing either value, but I will assume some values and do it in the longest way, and then, you just have to replace your values in the procedure to get the accurate result.
For this problem, I will assume the concentration of 3.5 mol/L and contains 180 g of perchlorate.
We need to know the volume in liters of this solution. We use the following expression:
M = n/V
From here, we solve for V:
V = n/M (1)
But we do not have the moles, but these can be calculated with:
n = m/MM (2)
So all we have to do, is to use the molar mass of perchlorate and calculate the moles. The reported molar mass for silver perchlorate is 207.32 g/mol so replacing in (2)
n = 180 / 207.32 = 0.8682 moles
Now that we have the moles, replace in (1) to get the volume:
V = 0.8682 / 3.5
V = 0.2481 L or simple 248.1 mL
This is the volume in this solution. Now replace your own data in this procedure and you should get the accurate result.
