Required for what? Required to do what? Required by whom? Required by what authority?
What are you trying to figure out? This could be a drinking water quality question for the municipal water authority, or a chemistry question [how much can you dissolve], or a whole number of other possibilities.
Also, so you mean Magnesium metal [Mg] or Magnesium Chloride [MgCl2]? To go along with the Potassium Chloride [KCl].

A 2 and a half -liters container is 7 tenths full What decimal fraction of 1 liters is required to fill it?
7/10 full means 3/10 empty.3/10 of 2.5 litres = 3 x 0.25 = 0.75 litre
How many 2 liters are in 30 dekaliters?
A decaliter is 10 liters, be definition. Hence, 30 decaliters is 300 liters. If you're using units of 2 liters, then you can fit 2 liters 150 times into 30 decaliters. 30 decaliters * (10 liters/decaliter) = 300 liters 300 liters / 2 liters = 150 units of 2 liters.
How many liters must be added to 637 liters to make one kiloliter?
363 liters
How many liters of compost required for container 2.4 meters square and 0.5 meters high?
A rectangular container with a square base of 2.4 meters on each sideand height of 0.5 meters has capacity of2.4 x 2.4 x 0.5 = 2.88 cubic meters = 2,880 liters.
What is half of 1.4 liters?
(1.4 liters) / 2 = 0.7 liters = 700 ml
0.133 mol of magnesium hydroxide is added to a 5.00 M solution of hydrochloric acid in a neutralization reaction that produces water and magnesium chloride How many liters of 5.00 M hydrochloric acid?
0.0532 L
What is the molarity of a solution made with 128 grams of magnesium chloride dissolved in one liter of water?
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
What mass of magnesium is required to produce enough gas to exert a partial pressure of 0.50 ATM in a 50.0 mL flask at a temperature of 25.0C?
To calculate the mass of magnesium required, we need to use the ideal gas law equation: PV = nRT. Given that the pressure is 0.50 ATM, the volume is 50.0 mL (which needs to be converted to liters), the temperature is 25.0C (which needs to be converted to Kelvin), and assuming 1 mole of gas is produced per mole of magnesium, we can solve for moles of gas (n). Then, using the molar mass of magnesium (24.31 g/mol), we can calculate the mass of magnesium required.
How many liters of oxygen are needed to produce 40 L magnesium oxide?
Magnesium oxide is a solid, not measured in litres.
How many moles of KCI would be dissolved in 4 liters of water to make a 2 Molar solution?
We need 8 moles potassium chloride.
How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
Molarity = moles of solute/liters of solution ( 300 ml = 0.300 liter ) 0.250 molar KOH = moles KOH/0.300 liters = 0.075 moles KOH
What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
What is body fluids?
You have 60 % water in your body weight for weight. 20 % is in extra cellular compartment and 40 % is in intro cellular compartment. So for 70 KG man you have 14 liters of fluid in extra cellular compartment. Out of this 3 liter is present in your blood. 11 liters is present in so called interstitial compartment. 28 liters is present in intro cellular compartment. Sodium chloride is the main salt in extra cellular compartment. Potassium chloride is the main salt present in intro cellular compartment. The osmolarity being about 150 Millimoles in your body fluid.

How many liters required for 280 miles at 27 miles to the gallon?
39.25 liters.
How much oil in liters required for sealed type 95 KV 1200mA - TR Set transformer?
That depends on the model of the transformer. I have seen transformers that required 7500 liters and some that needed 2,5 liters.
How many grams of sodium chloride is in 0.40 moles?
Molarity = moles of solute/Liters of solution ( 300 ml = 0.300 Liters ) For our purposes, Moles of solute = Liters of solution * Molarity Moles NaCl = 0.300 Liters * 0.15 M = 0.05 moles NaCl =============
