First You have to express the 200 g NaCl as moles of NaCl. The molar mass of NaCl is 58.5 g/mole. Consequently you need 200/58.5 g/(g/mole) = 3.42 moles of NaCl.
Having a 2.10 M NaCl solution You need 3.42/2.10 mole/(mole/l) = 1.63 l of the given solution.

What volume in ml of a 0.03455 M calcium hydroxide solution would be needed to completely react with 32.76 ml of a 0.0215 M phosphoric acid solution?
Volume mL= 32.76 mL x 0.0215 M/ 0.03455 = 20.386 mL calcium hydroxide solution.
How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
How many grams of calcium chloride would you add to water for a totoal volume of 500 ml to make a 5 percent solution?
Take 5 grams of calcium chloride and dissolve it in 100ml of solution to get a 5% solution of calcium chloride. The standard way to make a weight-volume solution is to take grams of the dry substance in 100ml of volume.

What volume of Albuterol Solution would be needed to prepackage 72 pints?
To determine the volume of Albuterol Solution needed to prepackage 72 pints you will need to know the volume of a single pint. Generally a pint is equal to 16 fluid ounces. Therefore 72 pints is equal to 1152 fluid ounces. To convert this to liters which is the common unit of measure for Albuterol Solution you will need to divide 1152 fluid ounces by 33.814. This will give you the volume of Albuterol Solution in liters needed to prepackage 72 pints which is 34.09 liters. 72 pints = 1152 fluid ounces 1152 fluid ounces divided by 33.814 = 34.09 litersIn conclusion the volume of Albuterol Solution needed to prepackage 72 pints is 34.09 liters.
