2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
A bottle of 450ml containing 10ppm of colloidal silver. Is that means that each 1ml contains 10ppm?. Thanks.
DDT is not soluble in water.
0.001%.
Your body can handle 10ppm (parts per million) for 8 hours. After that you are "hs2 saturated" and you body can't fight it a tenth as well. So to answer your question anything over 10ppm, or anything after 10ppm at 8 hours exposure.
Anything over 10ppm is not good
You add water to NaNO3 or NaNo3 to water until you reach the desired concentration
costly equipment and more expenaive chemicals.the turbidity should be below 10ppm.
10ppm of copper what mass of this rock must water flow. 10/10^6=2000/x=2E8 kg
take 1mg (0.001g) of mannitol and dilute it by deionised water to 100ml in 100ml measuring flask.The resulting solution is 10ppm.and then make further dilution to prepare required concentration.
Adora contains less then 3ppm of gluten...Less then 10ppm is considered "gluten free".. So, unless you are super sensitive to gluten, this product should be just fine..
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.
To get optimum active ingredients assay concentration easily through dilution procedure of different label claimed pharmaceutical product's. such as 10ppm. 20ppm etc.
