To dilute a 10 ppm solution to 1 ppm, you would mix 1 part of the 10 ppm solution with 9 parts of a diluent (such as water). This would result in a 1 ppm concentration because the concentration has been decreased by a factor of 10 during the dilution process.
To dilute 1000 ppm to 500 ppm, you need to add an equal amount of the solution without any concentration. For example, if you have 1 mL of the 1000 ppm solution, you would need to add 1 mL of water to make it 500 ppm.
Even a single drop of water will dilute 28 ppm of cyanide. Not by much, perhaps, but the question does not specify dilution to what degree.
10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
To convert 1 mg of benzole trozole in 100 ml methanol to ppm, we need to consider the molecular weight of benzole trozole. If we assume the molecular weight to be 150 g/mol, then 1 mg in 100 ml is equal to 10 mg/L or 10 ppm.
1000 ppm is equivalent to 1 milligram per milliliter.
10 ppm = 10/1,000,000 = 1/100,000 = 1/100,000*100% = 0.001%
To dilute 1000 ppm to 500 ppm, you need to add an equal amount of the solution without any concentration. For example, if you have 1 mL of the 1000 ppm solution, you would need to add 1 mL of water to make it 500 ppm.
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.
Make a 1 to 100 dilution of the original 1000 ppm solution. That is take 1 ml and dilute to 100 ml, or take 10 ml and dilute to 1000 ml. This will give you a 10 ppm solution.
10 ppm as a fraction is 10 / 1 000 000 = 0.00001, as a percentage = (10 / 1 000 000) * 100 = 0.001 %
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
yes. NO ! 1%
Depends on the printer and the settings, but usually around 1 ppm on best quality, about 5 ppm on normal quality, and about 10 ppm on draft quality. Laser printers, on the other hand, range from ~10 to ~100 PPM.
Even a single drop of water will dilute 28 ppm of cyanide. Not by much, perhaps, but the question does not specify dilution to what degree.
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
10 ppm = 10/1,000,000 =0.001/100 = 0.001%
