First, measure the volume, in liters, using the water displacement method. Next, look up the density of gold, which is 19,320 kg/m3. To convert to grams per liter, you simply need to multiply by 1, so the density is 19,320 g/l. Now you can calculate the mass from the density ...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in ...

To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. You then calculate molarity by measuring the volume of the solution...
Hence, the atomic mass is the sum of its protons and neutrons, which will be 12; therefore, 12u is the atomic mass of Carbon. Problem Sum to Calculate Atomic Mass Calculate the atomic mass of an element with an atomic number of 18 and a neutron number of 20. Solution: The number of...
How to calculate enthalpy of combustion Standard Enthalpy of Combustion:Standard enthalpy of combustion, {eq}\Delta H_c^{\theta} {/eq} is the enthalpy change when one mole of substance is burnt in plentiful oxygen under standard temperature and pressure....
Review how to calculate the mass of a liquid from its volume and density. Density is mass per unit volume: density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density...
This quiz and corresponding worksheet will help you gauge your understanding of how to calculate molarity and molality concentration. Topics you'll need to know to pass the quiz include understanding the moles of a solute per liter of a solution as well as knowing when molality is usually ...
there are two masses. The mass of the salt and the mass of the water are both needed to find the mass of the salt water. The mass of the salt is given, but the only the volume of water is given. We've also been given thedensity of water, so we can calculate the mass of the...
In Chemistry, you will often have to perform analyses of solutions. A solution consists of at least one solute dissolving in a solvent. Molality represents the amount of solute in the solvent. As the molality changes, it affects the boiling point and fre
