You would mix 1 part something with 99 parts something else, so if you were preparing a 1% solution of salt in water, you would put if you wanted to make 6.25 gallons of this, you would have 1 cup of salt and 99 cups of water.
You would wan to dilute the trisodium citrate in distilled water to create a 1% solution. So if you wanted 100mL of solution, you would mix 1mL of trisodium citrate with 99mL of distilled sterile water.
74389021790 is 100 percent 74389021790/100 = 743890217.9 is 1 percent. This value times 4 gives you the 4 percent. Solution: 2975560871.6
95000 is 100 percent. 95000/100 = 950 is 1 percent. This value times 5 gives you the 5 percent. Solution: 4750
644 Solution Method: 1% * 64400 = ? .01 * 64000 = 644
253000 is 100 percent. 253000/100 = 2530 is 1 percent. This value times 95 gives you the 95 percent. Solution: 240350
