- measuring the mass of this compound and the volume (or mass) of the solution
- by chemical analysis (and determination of the concentration of this compound)
If you know the molarity, multiply moles by molecular weight and adjust per the volume you have.
If you don't know the molarity, a simple means is to just evaporate the solvent and weigh the remaining compound
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
To calculate the grams of phosphate in a solution, you first need to determine the molarity of the solution. Once you know the molarity, you can use the molecular weight of phosphate to determine the grams present in the solution. Can you provide the concentration or volume of the K2HPO4 solution?
To calculate the concentration of a solution, you divide the amount of solute by the volume of the solution. This gives you the concentration in units such as moles per liter (M) or grams per liter (g/L).
To calculate the concentration of a solution, divide the amount of solute by the volume of the solution. This will give you the concentration in units such as moles per liter (M) or grams per liter (g/L).
To calculate the grams of NaOH in the solution, you first need to find the moles of NaOH present in 400.0 ml of the solution. The moles of NaOH can be calculated using the formula: moles = molarity x volume (in liters). Once you have the moles of NaOH, you can then calculate the grams using the formula: grams = moles x molecular weight.
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
Only a compound has a molar mass not a solution.
Calculate the mass (in grams) of sodium sulfide that is needed to make 360ml of a 0.50 mol/L solution
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound
5 mg of an element or compound in 1 L of solution

To calculate the molar mass, first find the molality of the solution using the boiling point elevation formula. Next, determine the moles of the compound by multiplying the molality by the mass of water in kg. Finally, divide the mass of the compound by the moles to get the molar mass.
By definition, a 10 molar solution contains 10 moles of the solute per liter of solution. Therefore, since 100 ml is 1/10 of a liter, 100 ml of such a solution would contain one mole of the solute. Physically, this would normally be accomplished by adding 10 grams, stated to be one mole of the solute, to a 100 ml volumetric flask, then adding pure water until the mark on the neck of the flask is reached.
To calculate the total amount of sodium chloride needed for a 13 L solution at 4 grams per liter, multiply the concentration by the volume of the solution: 4 grams/L x 13 L = 52 grams of sodium chloride. Therefore, you will need 52 grams of sodium chloride to make the 13 L solution.
