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 many grams of a drug must be used to prepare 3 liters of a 2 percent solution?
To prepare a 2% solution in 3 liters, you would need 60 grams of the drug. This is calculated by multiplying the volume (3 liters) by the percentage (2%) and converting the result to grams. 3 liters x 2% = 60 grams.
How many grams of dextrose are needed to prepare 0.5l of d5w?
To prepare 0.5L of D5W (5% dextrose in water), you need 25 grams of dextrose. This is because 5% of 0.5L is 25 grams.
How many grams of ammonium sulfate are needed to make a 0.25 molar solution at a concentration of 6 molar?
To prepare a 0.25 M solution of ammonium sulfate (NH₄)₂SO₄, you first need to determine the molar mass of ammonium sulfate, which is approximately 132.14 g/mol. For a 0.25 M solution, you need 0.25 moles per liter. Therefore, to make 1 liter of a 0.25 M solution, you would need 0.25 moles × 132.14 g/mol = 33.04 grams of ammonium sulfate. If you want to prepare a solution at a concentration of 6 M instead, you would need a significantly higher amount, specifically 6 moles × 132.14 g/mol = 792.84 grams for 1 liter.
How much gm of disodium edta require to prepare 0.05 m disodium edta solution?
To prepare a 0.05 M disodium EDTA solution, you would need to dissolve 3.72 grams of disodium EDTA dihydrate (Na2C10H14N2Na2·2H2O) in enough water to make 1 liter of solution.

You need 50 g of this drug.
How many grams of a drug must be used to prepare 3 liters of a 2 percent solution?
To prepare a 2% solution in 3 liters, you would need 60 grams of the drug. This is calculated by multiplying the volume (3 liters) by the percentage (2%) and converting the result to grams. 3 liters x 2% = 60 grams.
How many grams of I2 should be added to 750 g o C Cl4 to prepare a 020 m solution?
To prepare a 0.20 M solution of I2 in CCl4, you would need to calculate the moles of I2 required first. Molarity (M) = moles of solute / liters of solution. Since you know the molarity and volume of the solution, you can calculate the moles of I2 required and then convert that to grams using the molar mass of I2.
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 many grams needed from water to prepare 160 grams from potassium acetate 5 percent w?
To prepare 160 grams of potassium acetate with 5% w/w concentration, you will need 8 grams of potassium acetate (160 grams x 5% = 8 grams). Since potassium acetate is the solute in this case, you only need to consider the weight of the solute. The remaining weight will come from the water.
You need to prepare a 4M concentrated solution for a lab and only need 500 mL of total solution. If you use enough water to bring the volume to 500 mL how many grams of sodium chloride would you need?
