Hello,
I believe my calculations are correct, but I want to be sure before I proceed. I will just take two random liquids and ask my question as thoroughly as possible. So lets take olive oil and grapeseed oil. I want a solution that is 3% grapeseed oil, and another that is 15% grapeseed oil. So tell me if this is correct:
For a solution with a total volume of 30 milliliters, with a concentration of 15% grapeseed oil, I would put in 4.5ml of grapeseed oil and 25.5 ml olive oil?
For a solution with a total volume of 40 milliliters, with a concentration of 3% grapeseed oil, I would put in 1.2 milliliters of grapeseed oil and 38.8ml olive oil?
How about a total volume of 35 ml's, a concentration of 18% grapeseed oil. Would that be 6.3ml's grapeseed oil with
For some reason, it will not let me finish my post. The sentence was supposed to be 6.3ml's grapeseed oil with 28.7 ml's of olive oil. I know this is a basic question but I justwant to be sure I have the right formula for type of problem! Thank you very much!
your calculation is Right if the stock solution concentration of the oil 100 %
If your % is in volume than its ok but if its weight than you might need to consider it's density.
the concentration can be represented in weight % (g/mL) or volume %!!! if you are preparing solution with specific volume percentage, u need to prepare with standard flask! as the case the total volume of 30mL! u need to take 4.5mL of ur respective solute (grape oil) and it was made up to 30 mL with olive oil and its not always necessarily 25.5mL exactly!!!! please cross check!!! Thanks
