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.

How does one prepare 95 percent of ethanol from 100 percent?
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
Is .1 percent the same as 10 percent?
no. but, .1 is the same as 10 percent. .1 "percent" is different than just .1
How do you find a percent of a percent?
1 percent of a percent is 1/10000 or 0.0001; this is the same as saying 1 percent percent. Example: 5 percent percent is 0.0005, so 5 percent percent of 100 is 0.0005 x 100 or 0.05.
What is 1 100ths as a percent?
1/100 as a percent = 1%
How do you prepare a 1 percent solution?
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.
How do you prepare 1 percent of sodium citrate?
THE MEANING OF % IS 1 gm of substance in 100 mL of solvent.(w/v) so you can prepare 1 % sodium citrate by dissolving 1.0 g of Sodium citrate in to 100 ml of water.

For example, if a pH 4.9 buffer is desired, the second pKa should be used and the conjugate acid/base pair for this pKa is dihydrogen citrate and hydrogen citrate. Each of these conjugate acid/base concentrations can be multiplied by the overall volume desired to get the desired volume. However, if not all four compounds are readily available (which is quite common), each one can be generated with acid/base chemistry. For example, if only 1.0 M citric acid is available and 100 ml of 0.2 M pH 7.0 buffer is required, 0.2*0.100/1.0 = 0.02 L or 20 ml of citric acid should be used and (0.15985*3+0.04015*2) *0.100/1.0= 0.055985 L or 55.985 ml of 1.0 NaOH should be added to the citric acid to make the required amount of citrate and hydrogen citrate. This makes up for 75.985 ml and the rest 24.015 ml should be topped up with distilled water.
