How many formula units make up 23.6 g of magnesium chloride?
To determine how many formula units make up 23.6 g of magnesium chloride (MgCl₂), first calculate its molar mass, which is approximately 95.3 g/mol. Next, divide the mass of magnesium chloride by its molar mass: 23.6 g ÷ 95.3 g/mol ≈ 0.247 mol. Since one formula unit of MgCl₂ contains one magnesium atom and two chloride atoms, the number of formula units is Avogadro's number (6.022 x 10²³) multiplied by the number of moles: 0.247 mol x 6.022 x 10²³ ≈ 1.49 x 10²³ formula units.
How many mol make up 10.4 g of magnesium chloride (MgCl2)?
To calculate the number of moles of magnesium chloride (MgCl₂) in 10.4 g, first determine its molar mass. The molar mass of MgCl₂ is approximately 95.3 g/mol (24.3 g/mol for Mg and 35.5 g/mol for each Cl, with two Cl atoms). Using the formula ( \text{moles} = \frac{\text{mass}}{\text{molar mass}} ), we find that ( \frac{10.4 , \text{g}}{95.3 , \text{g/mol}} \approx 0.109 , \text{mol} ). Thus, 10.4 g of magnesium chloride contains about 0.109 moles.
How do you make 3 normal barium chloride?
To make a 3 M solution of barium chloride (BaCl₂), first calculate the required amount of BaCl₂ by using the formula: mass = molarity × volume × molar mass. The molar mass of barium chloride is approximately 208.23 g/mol. For example, to prepare 1 liter of a 3 M solution, dissolve 624.69 grams of barium chloride in enough water to make the total volume 1 liter. Always ensure to wear appropriate safety gear and follow proper lab protocols when handling chemicals.
What is the chemical equation for magnesium plus chlorine?
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.
How do you remove magnesium carbonate from table salt to make the salt totally pure?
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.
How do you make a dry sample of magnesium chloride crystals from magnesium carbonate and hydrochloric acid?
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.
How I will make 3 Molar solution of potassium chloride in 250 milliliter?
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.
How many formula units make up 25.2 g of magnesium chloride?
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.
How do you make salt with magnesium?
Add magnesium chloride to sodium chloride and mix.
How many formula units make up 33.8 g of magnesium chloride (MgCl2)?
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.
How many formula units make up 21.2g of magnesium chloride Mg Cl 2?
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.
How many formula units make up 12.2g of magnesium chloride?
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.
How many formula units make up 34.8 g of magnesium chloride?

How many grams of sodium chloride are required to make L solution with a concentration of M?
To find the grams of sodium chloride (NaCl) required to make a solution of a specific molarity (M) and volume (L), you can use the formula: grams = Molarity (mol/L) × Volume (L) × Molar Mass (g/mol). The molar mass of sodium chloride is approximately 58.44 g/mol. Multiply the desired molarity by the volume in liters and then by the molar mass to get the total grams needed.
How do you separate magnesium carbonate from a solution of magnesium carbonate and sodium carbonate?
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.
What kind of salt does Hydrochloric acid and magnesium hydroxide make?
Hydrochloric acid and magnesium hydroxide react to form magnesium chloride and water.
What does magnesium and iron chloride make?
most likely Magnesium-Chloride(MG?CL?) and Iron(FE?) The numbers depend on the oxidation states of iron and magnesium
