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 glucose are required to produce fifty milliliters of a 0.1 mole solution?
You need 0,9 glucose.
What is the weight in grams of a 0.5 N Na2CO3 used in determining the concentration of unknown HCl solution?
A 0.5N Na2CO3 used in determining the concentration of an unknown HCl solution has a weight of 1.06 grams. To find the weight, you need to first find out how many moles there are by calculating molarity times volume.
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
If we want to form 20.2 grams carbon dioxide how many grams of oxygen do we need?
We need 14,8 g oxygen.

How many Grams of Phosphate are in a 50 percent K2HPO4 Solution?
Need to know how much of the solution you have.
How many grams of NaCl are required to prepare 4000 mL of 5 percent solution?
14.575 round is 14.6 g
What is 4N NaOH?
The atomic weight of Na-OH is 23+16+1= 40. So to prepare the one N solution of Na-OH, you need to add 40 grams of Na-OH in one litre of water. To prepare the 4N Na-OH solution, you need to add 160 grams of Na-OH in one litre of water.

599.6
How many grams sugar need to be added in a 100mL water to make a 10 sugar solution?
To make a 10% sugar solution you need to dissolve 10 grams of sugar and bring the volume up to 100 ml
How many grams of sodium chloride are required to prepare 500.0 mL of a 100 M solution?
In this instance, 50 mol of sodium chloride is needed and molar mass of NaCl is 58.5 g/mol. Hence the mass we need is 29250 g. But this amount of salt could not be dissolved in 500 ml of water, so we cannot prepare this solution practically.
