How is the hfusion used to calculate the mass of solid that 1kj of enery will melt?
The heat fusion (hfusion) is the amount of energy required to melt a unit mass of a solid at its melting point without changing its temperature. To calculate the mass of solid that 1 kJ of energy will melt, you can use the formula ( m = \frac{Q}{hfusion} ), where ( m ) is the mass, ( Q ) is the heat energy (1 kJ in this case), and ( hfusion ) is the heat of fusion for the specific solid. By rearranging the formula, you can determine the mass that can be melted with the given energy.

How is the delta Hfusion used to calculate the energy needed to melt a mass of solid?
The delta Hfusion, or enthalpy of fusion, is the amount of energy required to convert a unit mass of a solid into a liquid at its melting point without changing its temperature. To calculate the energy needed to melt a specific mass of solid, you multiply the mass of the solid by the delta Hfusion value. The formula is: Energy = mass × ΔHfusion. This gives the total energy required to completely melt the given mass of the substance.

How is the delta h used to calculate the energy needed to melt a mass of solid?
The enthalpy change of fusion (ΔH_fus) represents the amount of energy required to melt a unit mass of a solid at its melting point. To calculate the total energy needed to melt a specific mass of solid, you can use the formula: ( Q = m \times ΔH_fus ), where ( Q ) is the total energy, ( m ) is the mass of the solid, and ( ΔH_fus ) is the enthalpy of fusion. By multiplying the mass by the enthalpy of fusion, you obtain the total energy required for the phase change from solid to liquid.
How is the delta H fusion used to calculate the mass of solid thatt 1kJ of energy will melt?
The delta H of fusion, or enthalpy of fusion, is the amount of energy required to melt a unit mass of a solid at its melting point. To calculate the mass of solid that 1 kJ of energy will melt, you can use the formula: mass = energy / ΔH_fusion. By dividing the energy (1 kJ) by the delta H of fusion (in kJ/kg), you can determine the mass of the solid that can be melted by that amount of energy.
How do you prepare ppm solution from solid?
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.

How is stoichiometery used to calculate energy absorbed when a mass of a solid melts?
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.

How can we calculate the density of a irregular solid or a liquid?
You can dip the irregular solid in a water or other suitable liquid. This is how, you can measure the volume of the solid. The mass can be measured by weighing scale. Mass/volume = density. It is easy to measure the mass and volume of the liquid. First measure the mass the container. Then add the liquid to it. You will get the mass of the liquid. Then measure the volume of the liquid. Use the above formula to calculate the density of the liquid.
