What are indications for using 5 percent dextrose in water?

D5W or Dextrose 5% Water is indicated for:. Rehydration . Provides calories for some metabolic needs (100ml provides 5g dextrose) -- useful in traumas when there's a shock related calorie burn. . By adding carbohydrates, reduces metabolism of proteins for calorie uptake. . May produce diuresis. (MORE)

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 (MORE)

What solution is the 5 percent Dextrose in Lactated Ringer's?

Dextrose is a synonym of D-glucose (also known as grape sugar, corn sugar, and when it's present in blood, blood sugar).In 2013, Dextrose 5 percent in lactated Ringer's injection wasrecalled. This recall stemmed from allegations of the producthaving mold in it.

What is dextrose solution?

Dextrose solution is a medication in an IV form used to supply water and calories to the body. It is also used as a mixing solution (diluent) for other IV medications

How many grams of NaOH are required to prepare 200 ml of a 0.450 M solution?

First you have to find the molar mass of NaOH which is,23+16+1=40g/mol. Then you take 0.450M X 200mL=90 mM. which can be converted to .090moles just move the decimal three decimal places. Then you take youmolar mass which is 40g/mol X .090moles= 3.6grams. (The molescancelled themselves out and your (MORE)

How many liters of a 10 percent alcohol solution must be mixed with 80 liters of a 80 percent solution to get a 50 percent solution?

The following solution is just an approximation, in practical circumstances sufficient to use. The addendum explains why. . x = number of litres (10%) to be added. You have 64 litres of alcohol in your original 80 litres. . 64 + x/10 = (80 + x)/2 . 640 + x = 400 + 5x . 4x = 240 . x = 60 and a (MORE)

50 percent dextrose solution and you need a 1 percent dextrose soultion. How do you figure that out?

If the percents given are by weight or mass, this is very straightforward: The ratio between the desired percentage and the initial percentage is 1/50. Therefore, a given mass of initial solution must be diluted to 50 times its original mass to obtain the desired lower concentration, or in other wor (MORE)

How much of a 37 percent formaldehyde solution should be put into 900 ml of water to make a 10 percent formaledhyde solution?

If the percentages specified are by mass and the 900 ml of water are assumed to be at standard temperature and pressure, this problem can be solved as follows: The 900 ml of water will have a mass of 900 grams. Call the unknown mass of the 37 percent solution to be added m. this will contain 0.37m g (MORE)

How many ounces of pure water must be added to 50 ounces at a 15 percent saline solution to make a saline solution that is 10 percent salt?

Add 25 oz of pure water Let X be the volume of pure water to add. Then the total amount of pure water you add plus the total amount of water in the 15% solution will equal the total amount of water in the final 10% solution. So, X + 50*(1-0.15) = (50 + X) * (1-0.10) X + 50*(0.85) = (50 + X)*(0.9 (MORE)

How many grams of Na2SO4 are needed to prepare 750 ml of a 0.375 M solution?

Let us find moles first. Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters ) 0.375 M Na 2 SO 4 = moles Na 2 SO 4 /0.750 Liters = 0.28125 moles Na 2 SO 4 === 0.28125 moles Na 2 SO 4 (142.05 grams/1 mole Na 2 SO 4 ) = 39.95 grams Na 2 SO 4 needed ------------- (MORE)

How many milliliters of a 50 percent acid solution and how many milliliters of a 20 percent acid solution must be mixed to produce 36 mL of a 30 percent acid solution?

A nswer:. 12mL of 50% solution and 24mL of 20% solution must be mixed to produce 36mL of a 30% acid solution. Let x = 50% acid solution. y = 20% acid solution. Equations:. x + y = 36mL ----equation (1). 0.5x + 0.2y = 0.3 * 36. 0.5x + 0.2y = 10.8. multiplying by 10. 5x + 2y = 108 ----equatio (MORE)

How many grams are KCl are required to prepare 250 ml of a 4M solution?

By definition, 1 liter of a 4 M solution must contain 4 moles of the solute. Because solutions are homogeneous mixtures and 250 ml is one quarter of a liter, the amount of KCl required is 1 mole. The gram molar mass* of KCl is 74.55 grams; this is therefore the amount of KCl required.** ____________ (MORE)
