Weight/Volume Percentage Concentration Calculations
w/v (%) = mass of solute (g)
A percentage concentration tells us how many parts of solute are present per 100 parts of solution. In weight per volume terms (mass per volume terms), this means a percentage concentration tells us the parts of solute by mass per 100 part

How to Make a 1 Percent BSA Solution
Reviewed by: Lana Bandoim, B.S.
When making a solution in a lab, there are different ways to express the concentration. Some of the most common ways are listed below:
Here, the focus will be specifically on how to make solutions with their concentrations expressed as weight by volume or w/v.
Why are there so many different ways to express concentration? Well, it’s because not all solutions are made the same way. For example, w/v is often used when a dry solute is weighed out and added to a liquid solvent. You can imag

To calculate the molarity of acidic solutions (wt/v%), Igenerally use the formula,
The obtained moles is the n.o. moles per litre solution, hence its molarity.

V soln for the solution volume in mL. M solute for the molar mass of the solute in g/mol. Therefore: Molarity = ( msolute V soln × 100%) × 1000mL/L 100% ×M solute. Or, rewriting in terms of %w/v and implied unit cancellation, we have: Molarity( mol L) = 1000 Msolute %w/v 100%. As an example, if we have a 37% w/v aqueous HCl solution, then:

Mass concentration of solution is expressed as % w/v for weight per volume. It can alternatively be abbreviated to m/v for mass per volume. This is used when a solid chemical is dissolved in a liquid. If 1g of potassium iodide is used to make up a total volume of 100ml, then a 1% w/v solution of potassium iodide has been made.

At the concentration you are using, there is no practical difference between w/w and w/v. The calculation is: w/v = w/w x Specific Gravity. A table for copper sulfate gives 20 g/l (2% w/v) a SG of 1.01. So, your solution would be ~ 1.001 SG. In other words, the difference would be in the order of 0.1%.
