My mom says that I can watch one more video before my bedtime.

[mjg]

I will never stop watching these videos.

Thank you orgo tutor. Once again you're making my chem courses a lot easier.

[acivi]

so if i get this right, you can basically say ppm = mg/L ?? because in general you don't have the density of a solution and furthermore, usually the density doesn't change a lot (e.g. in you example the result is 0.022, and without considering the density the result is 0.021, which is an error of 5%).

Nice! The legend of chemistry coming back at it again with the clutch!

Better than my lecturer by ppb, thanks so muchhh

[lakilaki]

Thank you so much! This video finally made me understand PPM

any video how to convert g/mol to ppm ?

Hi he Organic Chemistry Tutor, can you answer a question for me?
I've been reviewing this topic and it has made me super confused. I have 2 scenarios I hope you can clear up for me. I hope my wording is understandable.
First, some definitions:
A. *SolVENT*: the liquid that the (usually solid) substance is dissolved in, like water, oil or alcohol.
B. *SoLUTE*: the substance needing dissolving or diluting
C. *SoLUTION*: the final thing with both a solvent and a solute.

Question 1:
What is the definition of CONCENTRATION, amount of solute per solVENT or per final solution?
My issue:
Scenario 1:
Imagine I have 1 liter of water (solvent) and I have to use all of it. If I add 10g of salt, what is the concentration? Note, when you add the salt, the volume will increase and no longer be 1 liter.
This scenario is used in cooking, say I have a liter of soup and I want to add salt for flavour. I can have a recipe/ratio that says "Add 10g of salt for every 1 liter of soup". How would I summarise this statement? The concentration of salt for this recipe is ___?"

Scenario 2:
Imagine I dissolve 10g of salt in some water, then ADD ENOUGH WATER TO FORM EXACTLY 1 LITER, what is the concentration?

I haven't done wet lab stuff for a while now so I am confused, please forgive any errors below: I have definitely done both scenarios before, but cannot think of when I would do what. For scenario 2, from memory, the instructions in my handbooks would read " Make a solution of X in Y. What is the molarity of the SOLUTION?" and the way we would do this is, say, 1 in 10 would be X in (10-X) of Y, eg, 1g of salt in (10-1=) 9g of water = 10 gram overall, with the salt being 1/10 per gram of saline. This is used in serial dilutions, so that you might then have make 1 in 10, 2 in 10, 3 in 10 or 1 in 10, 1 in 100, 1 in 1000 etc.

So, now I am confused.When do you use which method, and, if a question is worded like "What is the concentration if you add 10g of salt to 1 liter of water?", what is the answer? Is it 10g of salt per Liter [of water] or is it 10g of salt per unknown liters of solution, since you don't know the new volume?

To convert parts per million (ppm) to parts per billion (ppb), you need to multiply the ppm value by 1000. This is because there are 1000 parts per billion in one part per million.

Here's the formula for the conversion:

ppb = ppm * 1000

For example, if you have a concentration of 5 ppm, you can convert it to ppb as follows:

ppb = 5 ppm * 1000 = 5000 ppb

So, 5 ppm is equivalent to 5000 ppb.

Thank you sir. I always watch your videos since High School

[aiueokaya]

Why do some express 1ppm as 1mg/L? not considering the density

[semira.abd.k]

best teacher ❤ iam teacher at chemistry department at uni. regard

[TheIGCSEChannel]

How do you upload so many videos so consistently tho I have huge respect for you :")

[do.notdisturb]

What if you’re not given the density of the solution

[aedaldaniel]

This video was confusing what about (w/v) he completely skipped that.

[sanadal]

million is smaller than a billion right? so when you convert from million to billion you should devide it by 1000

[pagescience]

Now, if I know the density of the solution and molar mass of the solute, I can change the ppm to molarity and change the molarity to ppm freely.
