How many gram of polyethelene glycole ointment base must be mixed with the contents of 22g tube of Bactroban oinment to prepare an oinment having concentraion of 5mg/g?? Plz help...n thank u.....

Answer: 22 g * 0.02 = 0.44 g Let x = number of grams of base After the mixing, we'll still have 0.44 g of 'stuff', we'll have (22 + x) g of the mix, and we want the concentration to be 5 / 1000 = 1/200. 0.44 / (x + 22) = 1/200 44/100 = (x + 22) / 200 44 = (x + 22) / 2 88 = x + 22 x = 66 Total of 88 g of mixture 0.44 / 88 = 44 / 8800 = 1/200 = 5/1000
