10% w/w = 10g/ 100g = x /3400g
x = amount of drug in 3400 g
or i would just say 10% of 3400 = 340 g of zinc oxide is needed to be 10% strength
now how much do you have to add of zinc oxide to get 15% strength??
so you will end up with 340g of original PLUS x amount of new zinc oxide = the total drug you will use.
so (340 + x)
and to find percentage of drug over entire medication ... you would say (340 + x) over (3400 + x)
and (3400 + x) = total medication with the additional zinc oxide you will want to add.
finally: total drug/ total medication(Rx) = the new percentage strength
sooo --> you wanted 15% to be the zinc oxide (drug)
(340 + x) / (3400 + x) = 15% drug
or better yet: (340 + x) / (3400 + x) = 15g/ 100g
since 15% is 15 out of 100
so CROSS MULTIPLY
and solve for x:
(340 + x) * 100 = (3400 + x) * 15
34000 + 100 x = 51000 + 15 x--> 85 x = 17000
x = 200 so 200 grams of zinc oxide must be added to the original to get your 15% of drug strength.
pillows contain barium hydroxide
Nitrogen dioxide is formed as a product of combustion; oxidation (reaction with oxygen) of organic compounds from fuel containing nitrogen.
% yield = 9.0/10.0 X100
Oxidation is mostly what occurs and rust is the by product but,this can take decades and even centuries
Oximes are Compounds containing OH group linked to the nitrogen atom, as we know like dissolves like, so this compound containing OH can be easily dissolved in alcohol, the product will be soluble in alcohol and easy to seperate.\
