a 2.5% solution has 25mg per ml, therefore a 20% solution has 200mg per ml.
A 1% solution normally contains 1 gram of active ingredient per 100 ml of solution (weight-volume percent) Could also be 1gm per 100 gms (weight-weight percent)- but normally weight-volume is used.
3.62 percent by mass means that there are 3.62 g NaOCl per every 100 g of solution. So, to find grams in 1911.9 g solution, just multiply ...3.62 g NaOCl/100 g soln x 1911.9 g soln = 69.2 g NaOCl
1 mL solution contain 1 mg potassium permanganate.
Percent concentration could mean many things...MOLARITY is defined as the moles of solute per unit volume of solution so 5 moles of NaCl in one liter of solution would be 5M (molar) NaCl solution.(Note: Solution is the solvent and solute combined, usually the solid is added and then the solution is filled to a certain line once the solid has dissolved.)MOLALITY is defined as the moles of solute per kilogram of solvent (NOT solution). So 5 moles of NaCl in one kilogram of water makes 5 mol/kg NaCl. (sometimes the symbol m is used for molality but is often confused with the unit of meters).For other types of "percent concentration" of solutions check:http://en.wikipedia.org/wiki/ConcentrationA cursory glance seemed to confirm the accuracy of the information.
No, not exactly.Mass mass percent concentration measures grams of solute per 100 grams of solution (= solvent + solute)Example:58.5 g NaCl (solute) added to941.5 g H2O (solvent) gives you1000.0 g solution of 5.85% NaCl (= 100%*58.5/1000.0),which is about a 1.0 mol/L NaCl solution.

One hundred and twenty is 240 per cent of 50.
add 4 parts water per part solution
20% 4 divided by 20 = 0.20 0.20 is 20% Four is one fifth of twenty. One fifth in a percent is twenty percent (20%), because percent means out of 100, and 100 divided by five equals twenty. If you would like to know why percent is called percent, it is actually very simple. PER - meaning out of, and CENT meaning 100. Out of 100.
1% solution = 1 gram per 100 mL, 10 grams per liter 20 grams
A quarter of 1 per cent or 0.0025
0.06% W/V = 0.06g / 100ml = 60mg/100ml = 0.6mg/ml
There are 128 ounces in a gallon. One percent of that is 1.28 ounces, or approximately one and one quarter ounces.

Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.
