A chemical formula can be used to determine the makeup of a substance. It tells you what elements make up a particular substance, like H2O is the chemical formula of water.
Based on the dissolution equation of BaSO4, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]
<h3>What is solubility product Ksp of a solute?</h3>
The solubility product, Ksp, of a substance is an equilibrium constant which expresses the product of the concentration of ions produced by a solute.
The solubility of a solute depends on temperature, thus solubility product also depends on temperature.
The balanced equation for the dissolution of barium sulfate is given below:
- BaSO4 ⇌ Ba^{2+} + SO4^{2-}
The solubility product for barium sulfate is given as;
Ksp = [Ba^{2+}] × [SO4^{2-}]
Therefore, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]

Boiling point is the temperature at which a liquid boils and turns to a gas.
Hope this helps!! (:
We can assume that the volume of one mole of any gas (within reason) is 22.4 L only if we know that the pressure of the gas is 1 atmosphere (101 kPa) and that the temperature of the gas is zero degrees Celsius (273 K). These are known as standard temperature and pressure (STP). So if the gas in question happens to be at STP then the calculation would be:
3.00 L x 1 mol/22.4 L = 0.134 mol
And 3.00 litres CO2 or any other gas at STP would contain 0.134 moles. If the gas was at some other temperature or pressure, assuming they were “moderate,” you could calculate the number of moles by solving the following formula for n.
PV =nRT Where P is pressure, V is volume, T is temperature in Kelvin and R is the ideal gas constant consistent with the units of volume and pressure used.
