How many grams of medication will 500 ml of a 10 percent solution contain?
50 grams
A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-v concentration of the solution?
W-V percent concentration g/mL = 1.20g/240mL = 0.005 g/mL percent
How many grams of Li OH are present in 8.0 mL of a 7.0 percent NaOH solution?
The answer is zero. You have asked the question incorrectly.
How many milliliter of a 20 percent and a 65 percent solutions should you mix together to make 500 milliliter of a 45 percent solution?
222.223 ml @ 20% solution = 44.444 ml 277.777 ml @ 65% solution = 180.555 ml total = 225 ml out of 500 ml = 45%
How much solvent must you add to 1 ml of a 50 percent solution to make a 10 percent solution?
4 ml
How many grams of medication will 500 ml of a 10 percent solution contain?
50 grams
What is the concentration of a solution consisting of 64 grams of calcium chloride in 250 mL of water?
64 (g) / 250 (mL) = 0.256 g/mL = 256 g/L
How many mL of water are present in 250 mL of a 15 percent by volume aqueous hydrochloric acid solution?
The water volume is 212,5 mL.
How many grams of a drug must be used to prepare 2 liters of a 1 percent solution?
1% solution = 1 gram per 100 mL, 10 grams per liter 20 grams
How do you calculate normality of percent solution?
Is the makeup of the solution expressed as "percent by mass"? If so, to calculate molarity (or normality), you have to also know the density of the solution Step 1. Lets say the solution is 14%, and the density is 1.09 g/mL. We can write the following: (14 grams solute/100 grams solution) (1.09 grams solution/ mL solution) Step 2. Multiplying and cancelling from step 1 gives you 15.26 grams solute / 100 mL solution. Multiplying top and bottom by 10 gives you 152.6 grams solute per liter. Step 3. Molarity is number of moles per liter. Divide the 152.6 grams of the solute by the forumua weight (or molecular weight) of the solute, and you have the number of moles of solute. This number is therefore the molarity of the solution. If the solution is "percent by volume", the number you have is number of grams per 100 mL. Multiply by 10, and you have grams per liter. Then divide by the formula weight, and you have the molarity.
How many grams of sodium chloride are needed to prepare 600 ml of a 0.9 percent saline solution?
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl
How many grams is 250 ml sugar?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
What is 250 grams of cream cheese in ml?
Approximately 250 ml, maybe just a bit less.
How many grams of the compound trinitrotoluene are needed to prepare 250 ml of a 0.100 M solution of the compound?
C7H5N3O6 Molarity = moles of solute/Liters of solution (250 ml = 0.25 Liters ) 0.100 M C7H5N3O6 = X moles/0.25 L = 0.025 moles -------------------------now, 0.025 moles C7H5N3O6 (227.14 grams/1 mole C7H5N3O6) = 5.68 grams TNT ====================a good firecracker!
What volume of 12M HCl solution is needed to prepare 250 mL of 0.100M solution?
25 mL
A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-v concentration of the solution?
W-V percent concentration g/mL = 1.20g/240mL = 0.005 g/mL percent
How many grams of Li OH are present in 8.0 mL of a 7.0 percent NaOH solution?
The answer is zero. You have asked the question incorrectly.
