Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
What is molarity of soultion containing 12.5g of Mgcl2 in 200 ml soultion?
MgCl2 Mg = 24.30 2Cl = 70.906 FW = 95.21 (Remember SigFigs) 12.5g ÷ 95g of MgCl2 = 0.131 moles of MgCl2 200mL = 0.200 L 0.131 moles of MgCl2 ÷ 0.200 L = 0.656 Molar Concentration
What is the molarity of0.73 g MgCl2 in 300 mL of solution?
To find the molarity, first calculate the number of moles of MgCl2 using its molar mass. Then, convert the volume from mL to L. Finally, divide the number of moles by the volume in liters to find the molarity.
Role of mgcl2 in DNA isolation?
MgCl2 is used in DNA isolation to help stabilize DNA molecules by reducing the repulsion between negatively charged phosphate groups in the DNA backbone. This allows the DNA to remain in solution and prevents it from degrading or sticking to other molecules during the extraction process. MgCl2 also helps to promote the enzymatic digestion of protein and RNA contaminants.
Is mgcl soulble?
It's MgCl2, and yes, it is soluble. It's an ionic compound, and ionic compounds are very polar. Water is polar as well, so magnesium chloride easily dissolves in water.
What is the molarity of a solution that is made by dissolving 75.0 grams of MgCl2 in 500.0 milliliters of solution?
Need moles MgCl2 75.0 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.7877 mole MgCl2 ================now, Molarity = moles of solute/Liters of solution ( 500.0 milliliters = 0.5 Liters ) Molarity = 0.7877 moles MgCl2/0.5 Liters = 1.58 M MgCl2 solution --------------------------------
How many moles of MgCl2 are present in 20.0 mL of 0.800 M MgCl2 solution?
Molarity = moles of solute/Liters of solution ( 20.0 ml = 0.02 Liters ) moles of solute = Liters of solution * Molarity 0.02 Liters * 0.800 M MgCl2 = 0.016 moles MgCl2 -------------------------------
What is the different between magnesium chloride solution and magnesium chloride crystals?
MgCl2 solution is obtained when it is dissolved in water whereas when it is in crystalline form then it is known as MgCl2 crystall.
MgCl2 will dissolve in water to form?
MgCl2 will dissolve in water to form magnesium ions (Mg2+) and chloride ions (Cl-) in solution.
Is MgCl2 soluble or insoluble?
MgCl2 is soluble in water. It will dissociate into Mg2+ and Cl- ions when dissolved in water, forming a clear solution.
What is the balanced chemical equation for magnesium chloride and sodium fluoride solution?
MgCl2(soln) + 2NaF(soln) ------> MgF2(s) + 2NaCl(aq)
Why is MgCl2 added to a solution of EDTA?
MgCl2 is added to a solution of EDTA to prevent the formation of insoluble metal hydroxides when titrating with EDTA. This helps to ensure that the EDTA only chelates with the target metal ions in the solution without interference from other metal hydroxides. MgCl2 acts as a masking agent for other metal ions present in the solution.
Is MgCl2 soluble?
Yes, in water, it dissociates into Mg2+ and 2Cl-
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 the molarity of 0.96 g MgCl2 in 0.500 L of solution?
To find the molarity, first calculate the moles of MgCl2 using its molar mass. Molar mass of MgCl2 = 95.21 g/mol Moles of MgCl2 = 0.96 g / 95.21 g/mol = 0.0101 mol Then, divide the moles by the volume in liters to find molarity: Molarity = 0.0101 mol / 0.500 L = 0.0202 M.
What aqueous solutions contains the greatest number of ions NaCl MgCl2 C6H12O6?
MgCl2 would contain the greatest number of ions in aqueous solution. Each formula unit of MgCl2 dissociates into three ions in solution: one magnesium ion (Mg2+) and two chloride ions (Cl-), giving a total of three ions per formula unit. NaCl would have two ions in solution (Na+ and Cl-), while C6H12O6 (glucose) does not dissociate into ions in solution.
How many ML equal 17.5 MG?
1 mole of MgCl2=95.21 grams (found on the periodic table) 17.5 g of MgCl2(1mole of MgCl2/95.21g of MgCl2)=.184 moles of MgCl2(grams cancel out and rounded to 3 sig. figs) .184 moles of MgCl2 (1 Liter/2.5 moles of MgCl2)=0.735L of MgCl2 (moles cancel and rounded to 3 sig figs) 0.735 L of MgCl2(1000 milliLiters/1 Liter)=73.5 mL of MgCl2 and round the answer to 2 sig figs which equals 74 milliLitersof MgCl2
