- 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 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 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 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.
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.
To calculate chloroform concentration, divide the mass or volume of chloroform by the total volume of the solution it is in. For example, if you have 5 grams of chloroform in 100 mL of solution, the concentration would be 5 grams / 100 mL = 0.05 g/mL or 50 mg/mL.
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
5 mg of an element or compound in 1 L of solution
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound

To create a 10 molar solution with a total volume of 100 ml for a compound with a molecular weight of 10 grams, you would need to dissolve 100 grams of the compound in enough solvent to bring the total volume to 100 ml. This calculation is based on the formula: molarity = moles of solute / volume of solution in liters. Given the molecular weight and desired molarity, you can calculate the mass of the compound needed.
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.

In a 70% dextrose solution, 70% of the total weight is dextrose. To calculate the grams of dextrose in 400ml of this solution, you would multiply 400ml by 70% (or 0.70) to find the amount of dextrose present.
To calculate the density of ammonia in the solution, you need to divide the mass of ammonia (24 grams) by the volume of the solution (3 liters). First, convert the volume to milliliters (1 liter = 1000 milliliters). Then, calculate the density by dividing 24 grams by 3000 milliliters. The density of the ammonia solution would be 0.008 g/mL.
