How many grams of a drug must be used to prepare 5000 milliliters of a 1 percent solution?
You need 50 g of this drug.
What is the percent concentration when 30gms of codeine is dissolved in 2 liters of solution?
The percent concentration of the codeine solution is 1.5%. This is calculated by dividing the mass of codeine (30g) by the total mass of the solution (2000g, since 1 liter of water is approximately 1000g) and then multiplying by 100.
How do you solve a student wishes to prepare 2 liters of 0.100 molar kio3 (molecular weight 214). the proper procedure is to weigh out?
42.8 grams of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 liters
How would you prepare 17.2 L of a 3.8 M HCl solution?
First get moles HCl, then get the grams HCl.Molarity = moles of solute/Liters of solution3.8 M HCl = X moles/17.2 Liters= 65.36 moles HCl===============so,65.36 moles HCl (36.458 grams/1 mole HCl)= 2382.89 grams HCl======================and,put this amount, 2382.89 grams, 65.36 moles HCl into the 17.2 liters of solution ( water, I suppose ) 2382.89 grams = 2.38 kilograms. I suppose you could weigh out the HCl in a flask of some sort.

0.1125% of polymer solution.
What weight of glucose is required to prepare 2 L of a 5 percent weight to volume solution?
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
How much salt does it take to reach 35 percent salinity in 4 liters of room temperature water?
To achieve a 35 percent salinity in 4 liters of water, you would need to dissolve 1.4 kilograms (or 1400 grams) of salt. This is calculated by determining that 35 percent of 4 liters (which is equivalent to 4000 grams, since 1 liter of water weighs approximately 1000 grams) is 1400 grams. Therefore, dissolving 1400 grams of salt in 4 liters of water will yield a 35 percent saline solution.
How many grams of a drug must be used to prepare 5000 milliliters of a 1 percent solution?
You need 50 g of this drug.
How will you prepare 3 liters of 2.5 M solution of KCl solution in water?
To prepare 3 liters of a 2.5 M solution of KCl, you would need to dissolve 187.5 grams of KCl (3 liters * 2.5 moles/liter * 74.55 g/mole) in enough water to reach a final volume of 3 liters. First, measure out 187.5 grams of KCl, add it to a suitable container, and then add water gradually while stirring until the final volume reaches 3 liters. Finally, mix the solution thoroughly to ensure the KCl is completely dissolved.
What is the percent concentration when 30gms of codeine is dissolved in 2 liters of solution?
The percent concentration of the codeine solution is 1.5%. This is calculated by dividing the mass of codeine (30g) by the total mass of the solution (2000g, since 1 liter of water is approximately 1000g) and then multiplying by 100.
How many grams of NaCl are required to prepare 4000 mL of 5 percent solution?
To prepare a 5% NaCl solution, you will need 200 grams of NaCl for 4000 mL (4 L) of solution. This is calculated as 5% of 4000 mL, which equals 200 grams.
