1 gram of medication. the container label reads 250 mg. how many tablets?
I think there is 1000mg in a gram, so that would be four tablets if they are 250mg each.
Is solubility Measured in grams of solute per gram of solution?
Solubility may be measured in grams of solute per gram of SOLVENT (not solution)
Can solubility be measured in grams of solute per gram of solution?
Yes.
What 0.25 g to mg?
250mg [0.25x1000]
Convert 60 percent solution to 40 percent solution?
All percentages are in mass% and all quantities are in grams (mass), be sure do not to take volumes into account because mass is 'additive', volumes are not quantitatively additable!Answer: Take whatever mass of 60 percent solution you have, multiply that mass by 20 (=60-40) and then divide that amount by 40, this is how much water to add to get an 40% solution.Example: Suppose you have 100 gram of 60% solution, then you should add:100 * (60-40)/40 = 100*0.50 = 50 gram of water; this is to be added to 100 gram of 60% solution to get (50 + 100 =) 150 gram of 40% solution.(see on top of the page to know why this calculation method is not valid for 'volumes')
