What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
How do you prepare 3 ppm solution of ferric chloride in 1000 liter water?
Just take 3 grams and add this to 1000 litres (= 1,000 kg = 1,000,000 (million) grams)
A sample of dry air contains 210 mL of oxygen 780 mL of nitrogen and 10.0 mL of all other gases What is the pressure in mm of Hg due to the nitrogen if the total pressure was 1000.0 mm?
Dalton says: "The partial pressure of a (non-condensing) gas in the mixture is proportional to its concentration." Since your total pressure is 1000 mmHg and the volumes all total to 1000 mL, you don't even need to take your shoes off to do the math.The nitrogen's volume is 780 ml of the total 1000 ml so its partial pressure is 780 mmHg of the total 1000 mmHg.
How do you prepare the 1.25 H2SO4 from 98 ww H2SO4?
Mix 120 g sulfuric acid with water to 1000 mL.
How many ml of 6.00m hcl are needed to prepare 1000 ml of a 100m hcl?
100 M HCl don't exist.
How do you prepare 1000 ppm sodium nitrite solution?
Weigh 1.499gm of pure Sodium Nitrite Standard (Purity>99%) in an A class volumetris flask and dissolve completly in double distilled water up to the mark.
How do you prepare 1000 ppm sodium nitrite?
1. Weigh 0,1 g of dry ultra pure sodium nitrite (NaNO2) on a metrologically checked analytical balance. 2. Dissolve the weighed sodium nitrite in 1oo mL distilled water in a 1 L volumetric flask. 3. Put the volumetric flask in a water bath at 20 0C and maintain at this temperature 30 min. 4. Add slowly distilled water up to the mark. 5. Put the cap on the flask and stir vigorously 1 min. 6. Transfer the solution in a glass or plastic container. 7. Attach a label with: name and concentration of the solution, data, name of the operator.
How do you prepare 1000 ml 0.01 M sodium sulphate?
Dissolve 1,42 g of anhydrous, for analysis sodium sulfate in 1 L demineralized water at 20 oC, in a volumetric flask.
How do you prepare a primary standard solution of 0.0500 M sodium carbonate?
use the equation that is standard: 1000 ml 1 M solution= (MOLECULAR WEIGHT) X ml 0.05 M solution = ((MOLECULAR WEIGHT)*X*0.05)/1000
How to prepare 1000 ppm chloride solution from sodium chloride?
1000 ppm Cl- = 1.0 gram per liter Cl- = 1.0 * [58.5 (gNaCl/mole NaCl)] / [35.5 (gCl-/mole NaCl)] = 1.65 g/L NaCl
1 kg of liquid nitrogen equals how many cu meter nitrogen gas?
1000 liters
How do you prepare 2 ppm solution of nickel nitrate?
how to prepare 1000 ppm solution of nickel carbonate
What is the ratio of oxygen to nitrogen in air?
The ratio is approx 268 to 1000.
A can of soda has 35 mg of sodium in it How many grams of sodium is this?
MG stands for milligram.milli means thousand.so 1000 MGs make 1 piece of Gram.so: 35MG/1000 =0.035 OF 1 GRAM Which in simple means you need 28.57 cans of soda to make 1 gram of sodium (1000/35=28.57)

Is the tank for compressed nitrogen the same as a tank for liquid nitrogen?
no. Compressed nitrogen need not be insulated. Liquid nitrogen is always insulated. Typically compressed nitrogen is stored at high pressure(over 1000 psi) and liquid nitrogen is kept at less than 100 psi.
