Subject: quantity in a 3ml syringe
Name: Tony


I'm mixing a formula of:

48 oz distilled water.
15 grams of Hydroxy Ethyl Cellulose GR (powder)
30 grams of Hydroxy Ethyl Cellulose MR (powder)
200 grams of Barium Sulfate (powder)
1000 grams of Calcium Hydroxide (powder)

After mixing, I need to estimate the amount of each ingredient that fits in a 3ml syringe. And how many syringes I can fill?

Hi Tony

I looked in a reference book and found that
1 ounce (volume) is 2.957353x10-5 m3
Since 1 m = 102 cm, and 1 cm3 = 1 ml it follows that 1 m3 = (102)3 cm3 = 106 ml. Thus 1 oz = 2.957353x10-5 m3 = 2.957353x10-5x106 ml = 29.57353 ml. Hence 48 oz = 1419.52944 ml. Since 1419.52944 divided by 3 is 473.17648, 48 oz will fill 473 3ml syringes.

If you assume that the powders are disolved or thoroughly mixed then the amount of each in a 3ml syringe is the amount in the entire mixture divided by 473.17648.
