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.
95000 is 100 percent. 95000/100 = 950 is 1 percent. This value times 5 gives you the 5 percent. Solution: 4750
74389021790 is 100 percent 74389021790/100 = 743890217.9 is 1 percent. This value times 4 gives you the 4 percent. Solution: 2975560871.6
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

See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.

You need 50 g of this drug.
1% solution = 1 gram per 100 mL, 10 grams per liter 20 grams
To prepare a 1% iodine solution, you can mix 1 part iodine with 99 parts water (for example, 1 mL iodine to 99 mL water). Ensure proper handling and measuring equipment to accurately dilute the iodine. Remember to always label the solution properly for safety and tracking purposes.
90 ml of dextrose and 4.41 litres of water.
To prepare a 1% phenolphthalein solution in 2000mL, you would need to dissolve 20g of phenolphthalein in 2000mL of solvent (usually water or alcohol). This will result in a 1% solution by weight/volume. Remember to wear appropriate personal protective equipment and handle chemicals with care.
To prepare 1 liter of a 5% alcohol-water solution, you would mix 50 mL of alcohol with 950 mL of water. This ratio would give you a total volume of 1 liter with 5% of it being alcohol.
Check what it is dissolved in first and use the same solvent for dilution. If you want to make a litre of 10% for instance, You want to dilute it 10 in 26 parts or 5 in 13. So 1 litre /13*5 is 384.6ml of 26% ammonia, and dilute to 1 litre with solvent
125 ml 500(ml) * 0.05 = 25 25 / 0.20 = 125
