How many kilos of Magnesium and Potassium Chloride required in 21000 liters of water?
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].
What else can I help you with?
A 2 and a half -liters container is 7 tenths full What decimal fraction of 1 liters is required to fill it?
Well, honey, if the container is 7 tenths full, that means it has 1.75 liters in it. To fill it up to 2.5 liters, you would need 0.75 liters more. So, the decimal fraction of 1 liter required to fill it would be 0.75. Hope that clears things up for you, darling!
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
What is half of 1.4 liters?
(1.4 liters) / 2 = 0.7 liters = 700 ml
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 the molarity of this potassium chloride solution?
To determine the molarity of a potassium chloride solution, you need to know the moles of potassium chloride dissolved in a liter of solution (mol/L). It can be calculated by dividing the number of moles of potassium chloride by the volume of the solution in liters.
What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
To calculate the molarity, you first need to find the moles of magnesium chloride using its molar mass. The molar mass of magnesium chloride is 95.21 g/mol. Next, use the formula Molarity = moles of solute / liters of solution to find the molarity. Convert 250 ml to liters (0.25 L) and then calculate the molarity.
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?
To calculate the molarity, first determine the molar mass of magnesium chloride, which is 95.211 g/mol (24.305 g/mol for Mg and 35.453 g/mol for Cl). Next, calculate the number of moles of magnesium chloride in 128 grams by dividing the mass by the molar mass. Then, divide the moles by the volume of the solution in liters to get the molarity. So, the molarity of the solution would be about 1.34 M.
How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
To calculate the moles of potassium hydroxide needed, use the formula: moles = molarity * volume (in liters). First, convert 300 mL to liters (0.3 L). Then, moles = 0.250 mol/L * 0.3 L = 0.075 moles of potassium hydroxide needed to prepare the solution.
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?
Can use the ideal gas law to find moles magnesium. Pressure * volume = moles * R, a constant * temperature Kelvin PV = nRT some conversion needed 50.0 ml = 0.05 Liters 25.0 C = 298.15 Kelvin (0.50 atm)(0.05 Liters) = (moles Mg)(0.08206 L*atm/mol*K)(298.15 K) 0.025/24.466 = moles Mg = 0.0010218 moles Magnesium Now, 0.0010218 moles magnesium (24.31 grams/1 mole Mg) = 2.48 X 10^-2 grams of magnesium required ------------------------------------------------------------
What is the molarity of a solution that contains 93.5g of potassium chloride dissolved in 500ml of solution?
To find the molarity, you first need to calculate the number of moles of potassium chloride using its molar mass. Then, you can divide the number of moles by the volume of solution in liters to get the molarity. In this case, you would first convert 93.5g to moles, then divide by 0.5L to find the molarity.

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 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 =============
How many liters required for 280 miles at 27 miles to the gallon?

What fluids the body?
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.
