Which solution of heparin is more concentrated 1000 or 10000?

A heparin solution with a concentration of 10,000 units/mL is more concentrated than a solution with a concentration of 1,000 units/mL. This means that the 10,000 units/mL solution contains a higher amount of heparin per milliliter compared to the 1,000 units/mL solution.


If you have a stock solution of 50ul at a concentration of 50 ul per ml and need a final concentration of 2 ul per ml how would you work this out?

You need to add the 50ul stock solution to 1200ul of distilled water to produce 1250ul of solution with a concentration of 2ul per ml.


What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?

The final percent concentration of the solution would be approximately 12.0% methanol. This is calculated by dividing the volume of methanol by the total volume of the solution (600 ml / 5000 ml) and then multiplying by 100 to get the percentage.


How would you prepare tetracycline stock solution?

To prepare a tetracycline stock solution, you would weigh out the appropriate amount of tetracycline powder and dissolve it in a suitable solvent, such as sterile water or ethanol. The concentration of the stock solution will depend on your experimental needs, but typically a concentration of 10-50 mg/ml is common. Remember to sterile filter the solution before storing it in aliquots at -20°C to prevent degradation.


Calculate the concentration of a 500 ml solution of sucrose and water containing 125 mg of sucrose Show your calculations?

To calculate the concentration of the sucrose solution, you would divide the amount of sucrose (125 mg) by the total volume of the solution (500 ml) and then convert the units as needed: Concentration of sucrose solution = 125 mg / 500 ml = 0.25 mg/ml = 0.25 g/L

How do you calculate chloroform concentration?

To calculate chloroform concentration, divide the mass or volume of chloroform by the total volume of the solution it is in. For example, if you have 5 grams of chloroform in 100 mL of solution, the concentration would be 5 grams / 100 mL = 0.05 g/mL or 50 mg/mL.


What is the volume percent concentration of propanol in a solution made by mixing 100 mL of propanol with 0.30 L of water?

To calculate the volume percent concentration of propanol in the solution, we first need to find the total volume of the solution. This would be the sum of the volumes of propanol and water: 100 mL + 300 mL = 400 mL. The volume percent concentration of propanol in the solution is then calculated by dividing the volume of propanol by the total volume of the solution and multiplying by 100: (100 mL / 400 mL) * 100 = 25%. Therefore, the propanol concentration in the solution is 25% (v/v).

What is the mass of DCPIP powder needed to form 300 mL of 1percent DCPIP solution and all measurements in grams and millilitres?

To make a 1% solution of DCPIP in 300 mL, you would need 3 grams of DCPIP powder. This is because 1% of 300 mL is 3 mL, and the density of DCPIP powder is generally close to 1 g/mL. So, 3 grams of DCPIP powder dissolved in 300 mL of water would give you a 1% DCPIP solution.


What is the concentration of a solution expressed in g 100ml if 25 g of solute is dissolved in 40 ml of water?

The concentration of the solution is 62.5 g/100ml. This is calculated by dividing the mass of solute (25g) by the volume of solution (40 ml) and then multiplying by 100 to express the concentration in grams per 100 ml.

How many grams of sugar must be dissolved in 150 mL of water to make a solution that has a concentration of .6 g?

For a concentration of 0,6 g sugar/1000ml: 15 ml for 150 mL.


How many ml equals to 20 meq of potassium?

To convert milliequivalents (meq) of potassium to milliliters (ml), you need to know the concentration of the potassium solution being used. For example, in a common potassium chloride solution, 1 meq of potassium is approximately equal to 0.5 ml of a 2 mEq/ml solution. Therefore, 20 meq of potassium would equal about 10 ml in that concentration. Always check the specific concentration of the solution for accurate conversions.


What is the concentration of a 450mL solution that contains 200 grams of iron II chloride?

The concentration of the solution is calculated by dividing the mass of the solute by the volume of the solution. In this case, the concentration of the iron II chloride solution is 200 grams divided by 450 mL, which is approximately 0.44 grams/mL.
