To calculate the molar heat of solution of zinc chloride, we use the heat evolved by dissolving 1 gram of ZnCl2 in water. First, we convert the mass of ZnCl2 to moles using its molar mass of 136.3 g/mol. Then, we divide the heat evolved by the number of moles dissolved to get the molar heat of solution. In this case, the molar heat of solution would be 3.89 kJ/mol.

What is a substance dissolved to form a solute?
The solute.
Is The substance being dissolved in a solution is called a solvent.?
No, the substance being dissolved in a solution is called a solute. The solvent is the substance that does the dissolving.
How do you show that a substance is dissolved in water when writing the equation?
You can represent a substance dissolved in water by placing the chemical formula of the substance in parentheses followed by "(aq)" to indicate that it is in aqueous solution. For example, sodium chloride dissolved in water would be written as NaCl(aq).
What is a solute give example?
A solute is a substance that is dissolved in a solvent to form a solution. An example of a solute is salt (sodium chloride) being dissolved in water to create a saltwater solution.
What is a mixture in which one substance is dissolved in another?
A mixture in which one substance is dissolved in another is called a solution. The substance that is dissolved is called the solute, and the substance in which it is dissolved is called the solvent. Solutions can be in the form of liquids, gases, or solids.
Calculate the molarity of a solution that contains 35.0g of barium chloride dissolved in 450.0ml solution?
2.5
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.
Substance that is dissolved in a solution?
The substance that is dissolved in a solution is called a solute. It is typically present in smaller quantities compared to the solvent, which is the substance that dissolves the solute in the solution.
Is salt solution?
Salt water is a solution because it dissolves and in solutions, the solute is the substance that is dissolved and the solvent is the substance in which the solute is dissolved. So is Salt water a solution yes.
Is the substance that is dissolved in a solution?
The substance that is dissolved in a solution is a solute. A solvent is the dissolving medium in a solution.
What is composition solution?
A solution is formed from the solute (the substance dissolved) and the solvent. Example: in the salted water sodium chloride is the solute and water is the solvent.
Is The substance being dissolved in a solution is called a solvent.?
No, the substance being dissolved in a solution is called a solute. The solvent is the substance that does the dissolving.
What is a substance in which a solute is dissolved to form a solution?
A solvent is a substance in which a solute is dissolved to form a solution. The solute can be solids, liquids, or gases that are dissolved in a solvent to create a homogeneous mixture. Examples include water (solvent) dissolving salt (solute) to form a saltwater solution.
What is sodium chloride solution?
This solution contain a specified concentration of sodium chloride.
When sodium chloride is dissolved in water the solution is homogeneous?
The sodium chloride solution of sodium chloride in water is homogeneous.
What do you calll the substance in a solution that dissolved?
The substance dissolved is called the solute. The substance that the solute is dissolved INTO is called the solvent.
What is a mixture in which one substance is dissolved in another?
A mixture in which one substance is dissolved in another is called a solution. The substance that is dissolved is called the solute, and the substance in which it is dissolved is called the solvent. Solutions can be in the form of liquids, gases, or solids.
