Thank you! The textbook we were assigned did a very bad explaining this concept so I had to look it up. I'm glad I ran into your video first

Hi Kuldeepak, Thanks for watching my videos. Since your answers has to come out in a whole number, you have to play around with this problem a bit. I started off with measuring out 2 mL of HCl because that is the minimum we can measure. I then added 6 mL of water for a total of 8 mL. Now you can set up a simple ratio proportion problem to see if the answer comes out with something that will work. 2 mL HCl/10 mL soln = 0.5ml HCl/X mL soln. Solving for X we get 2 mL, which we can measure.

You can download my book, Pharmacy Calculations for Pharmacy Technicians: Solving Pharmacy Calculation Problems Without All the Silly Formulas, for free at payhip.com/b/5xVY. It goes into more detail than possible on the videos and is full of practice problems and answers.

A 10-milliliter graduate weighs 42.745 grams. When 5 milliliters of distilled water are measured in it, the com- bined weight of graduate and water is 47.675 grams. By definition, 5 milliliters of water should weigh 5 grams. Cal- culate the weight of the measured water and express any deviation from 5 grams as percentage of error

Thanks for sharing valuable things. Would you help me solve this problem. A formula calls for 0.5 milliliter of hydrochloric acid. Using a 10-milliliter graduate calibrated from 2 to 10 milliliters in 1-milliliter divisions, explain how you would obtain the desired quantity of hydrochloric acid by the aliquot method.

Let me start off by saying "Thank you" I got my Natonals not too long ago and I am reviewing your posts in order to refresh my self and to move further in my career. My question is about using shortcuts in particular with the last question. I came up with the 1.6 g range by simply multiplying 80 g by 2%, Would you recommend using such a shortcut for other problems ?
@BradWojcikPharmD

Hi Russell. I am happy that I could help. Yes, multiplying by 2% is fine. It is essentially what was done in the video. I just don't like other shortcuts like moving the decimal point to convert units, because it is too easy to move it the wrong direction.
