I require help verifying my math to be sure its correct? I need my solution accurate as possible.
Please help with a math question. I was making a 309mg solution I realized adding powder to liquid will increase the volume hence the solution will be slightly lower in potency than intended. So I googled the weight of propylene glycol to figure out the math to make a more accurate dose. I’m not sure if my math is correct though can anyone verify please?
1ml propylene glycol weighs .965g
THE powder used weighs .309g
For a solution of 5mg/ml I put .309g powder into 62ml propylene glycol
Weight is .309g powder + 59.8g propylene glycol (62x.965) or total weight of 60.109g
So actual volume of solution in mls is 60.109g ÷ .965g = 62.29ml (powder upped volume by .29ml)
So adjusted dosage of my solution is 309mg powder ÷ 62.29m. = 4.96mg/ml
Let me know if my math above ^ is incorrect thank you.
