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%)
no. but, .1 is the same as 10 percent. .1 "percent" is different than just .1
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.
1/100 as a percent = 1%
NO. 1 percent is less than 5 percent.
To prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
To prepare a 1.25 M solution of sodium citrate, dissolve 294.1 grams of sodium citrate dihydrate powder in 1 liter of water. Mix well until the powder is completely dissolved. Adjust the volume if necessary to reach exactly 1 liter.

To prepare 0.2M citrate buffer for the mentioned pH values, you need to weigh the appropriate amount of citric acid and trisodium citrate dihydrate and dissolve them in distilled water. Use a pH meter to adjust the pH to the desired values by adding small amounts of citric acid or sodium hydroxide. Be cautious as adjusting the pH too much can change the ionic strength of the buffer.

Sodium citrate is composed of around 13% sodium by weight. This means that 1 gram of sodium citrate contains roughly 130 milligrams of sodium.

Yes, Bacillus amyloliquifaciens typically shows a positive reaction for citrate utilization due to its ability to metabolize citrate as a carbon source. This can be confirmed using citrate utilization tests in a laboratory setting.
Typically, you would use enough water to dissolve the desired amount of ammonium citrate completely. The ratio of water to ammonium citrate can vary based on the specific recipe or application, but a common guideline is to use approximately 1 part ammonium citrate to 3 parts water by weight.
