5ml of the 1000 ppm solution in 95ml distilled water gives a 500ppm solution
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.
1 GPG = 17.1 PPM
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
dilute it 1 in 5000. likely best done with a serial or step dilution
5ml of the 1000 ppm solution in 95ml distilled water gives a 500ppm solution
10 ppm = 10/1,000,000 = 1/100,000 = 1/100,000*100% = 0.001%
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.
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
