The SpG of a 75% Phosphoric Acid Solution @ 20C is 1.579.SO ...1.579 X (8.33 lb/gal of water) = 13.2 lb/gal.
Folic acid supplementation beginning at least 3 months before conception and continued through at least the first trimester of fetal development has been shown to reduce the incidence of spina bifida by almost 75%.
the purity of the acid is 25%
Vitamin B9 (Folate) deficiency can lead to neural tube defect (NTD) and the main source of it is green vegetables. That's why any woman who plans on getting pregnant should consume sufficient amounts of B9 because the neural tube closes 27 days after conception meaning before a woman even knows she's pregnant!
At this time there is no cure for Spina Bifida. There are surgeries to treat some of the medical issues involved with the defects; doctors can shunt the excess fluid from the brain and cover the defect in the spine to prevent infection and further injury to the exposed spinal cord and nerves. Research shows a daily dose of 4mg of folic acid (Vitamin B9) taken by women at risk, starting one to three months before conception and continued through the first trimester reduces the risk of having a baby with the defect up to 75%. Continued use of folic acid during pregnancy may reduce the severity of the defects when they do occur. Folic acid .4mg taken one month prior to conception and through out the first trimester reduces the risk of having a baby with Spina Bifida to about 1% in women with no known risks.
75 = 75
The Aspicol 75 medicine is used in the prevention or the treatment of acid indigestion and the sour stomach.
75 ml is 75 ml
1.5
This may be a coincidence that this number keeps popping up. It maybe that the acid you are using has an atomic mass weight of 75. And if you are always using this acid then 75 will always pop up. See related link for a little more info
The total volume of the new acid solution is 75 mL, and this solution is 65%, so the amount of acid in this solution is (0.65)*75mL = 48.75 mLYou have two equations and two unknowns:x + y = 75(0.40)*x + (1)*y = 48.75 {0.40 represents 40% and 1 represents 100% pure}Solve and get x = 43.75 and y = 31.25, so you need 43.75 mL of the 40% acid and 31.25 mL of the pure acid.
