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

How can you express the concentration of a substance mathematically?
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.

What does Magnesium chloride and water form?
When magnesium chloride is dissolved in water, it forms a clear liquid solution. This solution contains magnesium ions (Mg2+) and chloride ions (Cl-), which are the products of the dissociation of magnesium chloride in water.
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.
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.

First, calculate the number of moles of barium chloride using its molar mass. Then, convert the volume from milliliters to liters. Finally, divide the number of moles by the volume in liters to find the molarity of the solution.
Is magnesium chloride solid liquid aqueous or gas?
Magnesium chloride can exist as a solid, liquid, or aqueous solution depending on its physical state. Solid magnesium chloride is a crystalline substance, liquid magnesium chloride is a molten form, and aqueous magnesium chloride is a solution in water. It does not exist as a gas under normal conditions.
What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?
The molarity of a solution given by the number of moles divided by the volume it contains. Hence, the molarity of KCl is 4.00/3.00 = 1.33 mol/L.
What is the molarity of a solution that contains 55 grams of copper chloride dissolved in 1500 mL of water?
To find the molarity, we first calculate the number of moles of copper chloride using its molar mass. The molar mass of copper chloride is 134.45 g/mol. Then divide the mass by the number of moles and the volume in liters (1500 mL = 1.5 L) to get the molarity. The molarity of the solution is 0.20 M.
