Dissolve 95,211 g of anhydrous magnesium chloride for analysis in a 1 L volumetric flask at 20 oC.
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.
Magnesium carbonate is practically insoluble in water; dissolve the salt, filter the solution. Magnesium carbonate remain on the filter, the sodium chloride is now in solution. You can use this solution as table salt solution or by evaporation of the water you can obtain pure crystallized NaCl. But I think that it is more simple to buy pure sodium chloride; also, magnesium carbonate is not dangerous and is a common food additive.
When the mixture is heated the Ammonium Chloride(NH4Cl)fumes get separated, leaving the Magnesium Sulfate(MgSO4)behind. Be careful Ammonium Chloride sublimes or sometimes decomposes into poisonous gases Hydrogen Chloride(HCl) and Ammonia(NH3)
Need formula of magnesium nitride, an ionic compound. Mg2+ and N3- together make Mg3N2 -------------- so 3 * 24.31 g = 72.93 grams 2 * 14.01 g = 28.02 grams ------------------------------------------add = 100 .95 grams/mole --------------------------------molar mass magnesium nitride
Dissolve 17, 5 mg magnesium chloride anhydrous (reagent grade) in 1 L demineralized water, at 20 0C, in a vilumetric flask.
Firstly, you need to mix the two solutions together to form magnesium chloride, carbon dioxide and water. since carbon dioxide is a gas there is no need to chemically remove it. then you should evaporate the water from the solution and heat the salt slowly to crystalize the solution.
To make a 3 Molar solution of potassium chloride in 250 milliliters: Calculate the mass of potassium chloride needed using its molar mass. Dissolve this mass of potassium chloride in a small amount of water, then add water to bring the total volume to 250 ml. Stir to ensure complete mixing and dissolve the potassium chloride completely.
To determine the number of formula units, you need to first calculate the molar mass of magnesium chloride (MgCl2). The molar mass is 95.21 g/mol. Next, divide the given mass (25.2 g) by the molar mass to find the number of moles of magnesium chloride. Finally, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
Add magnesium chloride to sodium chloride and mix.
To find the number of formula units in 33.8g of magnesium chloride (MgCl2), you first need to calculate the molar mass of MgCl2. The molar mass of MgCl2 is 95.21 g/mol. Then, divide the given mass by the molar mass to find the number of moles, which is 0.355 moles. Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of formula units.
To calculate the number of formula units in 21.2g of magnesium chloride (MgCl2), first calculate the molar mass of MgCl2 which is 95.21 g/mol. Then, divide the given mass by the molar mass to get the number of moles (0.223 mol). As there is one mole of MgCl2 in 1 formula unit, 0.223 mol is equal to 0.223 formula units.
To determine the number of formula units in 12.2g of magnesium chloride, you need to first calculate the molar mass of magnesium chloride (MgCl2). The molar mass of MgCl2 is 95.21 g/mol. Next, divide the given mass (12.2g) by the molar mass of MgCl2 to find the number of moles present. Finally, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
molar mass of MgCl2=95.211g/mol mol=mass/molar mass=34.8g*mol/95.211g=0.3655039859molMgCl2 #of anything=mol*Avogadro's#=0.3655mol*6.022*1023formula units/mol answer= 2.20*1023
First of all, since Magnesium Carbonate is not Soluble in water you couldn't have a solution of these two salts in water. But if you had a mixture of the two in powdered form and need to separate them simply dissolve what you can in water, the part that wont dissolve is the magnesium carbonate and you could them filter it out and let the solution of sodium carbonate dry out and there you have the two separated.
Hydrochloric acid and magnesium hydroxide react to form magnesium chloride and water.
most likely Magnesium-Chloride(MG?CL?) and Iron(FE?) The numbers depend on the oxidation states of iron and magnesium
it would make magnesium chloride
