How much pure acid should be added to 50 ml of a 10 percent acid solution to give a 50 percent acid solution?
A 50 ml solution that is 10% acid will consist of 5 ml of acid (10% of the volume) and 45 ml of water (90% of the volume). You're not adding any water, but you want to add enough acid to make a solution that is 50% acid and 50% water. You will need to have a total of 45 ml of acid in the mixture to make it a 50/50 solution, since the amount of water is also 45 ml. You have 5 ml in there already, so you would need to add 40 ml of acid. That would make a total 90 ml solution that is 50% water (45 ml) and 50% acid (45 ml).
How much solvent is needed to make 200 ml of 50 percent rubbing alcohol?
200 ml X .50 = 100 ml
How many 355 ml does it take to fill a 1.0-m cubed tank?
1m = 100cm 1m3 = 1m x 1m x 1m = 100cm x 100cm x 100cm = 1000000cm3 1ml = 1cm3 => 355ml = 355cm3 In 1m3 to find the number of 355ml, divide by 355ml: 1m3 / 355ml = 1000000cm3 / 355cm3 ~= 2816.9
How many drops per minute in 50 ml and 10 drops per ml?
50*10 = 500 drops.

How many Ml of 14.5 M NH3 are needed to prepare 2.00 L of a 1.00 M solution?
M V = M' V' 1M x 2L = 14.5 M x V' V' = 138 mL
How do you prepare 500cm3 of NaHCO3 solution of 1M concentration?
Weighting half value of 23+1+12+(3x16) = 84/2 = 42 gram NaHCO3 gives you 0.5 mole of it, to be dissolved in about 200 mL and there after to be filled up to 500 mL (= 500 cm3) will result in a 0.5 mol / 500 mL = 0.5 mol / 0.5 L = 1 mol/L = 1M NaHCO3
How do you prepare 50 percent solution of potassium carbonate?

Is 1000 ml greater than 1000 cm?
They cannot be interconverted. A milliliter is a unit of volume while a centimeter is a unit of distance. a milliliter is equal to a cubic centimeter, however.
How do you prepare 1 molar tris?
To make 1.00 litre of a 1.00 M Tris buffer you take 121.14 g Tris and dissolve it by adding water up to 1.00 L (the molar mass of Tris is 121.14 g/mol, that's why) There is a point where you need to set the pH so, its wise to dissolve the given amount in 700 ml ddH2O, setting the pH to 7.5-8.0 using Conc. HCl and then making up the final volume to a litre. filter with 0.5 micron filter and autoclave.
