<span>Answer:
Mass % KCL:
Add the grams of both compounds (31.0 g KCL + 225 g water) to find total mass and then divide the grams of KCL over the total mass, then multiply by 100: ( 31.0 g KCL / 31.0 g + 225 G) * 100%
Mole fraction KCL
Calculate the moles of KCL and water and add them to find the total moles (Moles of KCL + moles of water). Then, divide the number of KCL moles over the total moles.
moles of KCL/ moles kcl + moles water= mole fraction of KCL</span>
Cl⁻ has a greater charge density than Na⁻.
The amount of electric charge that can build up across a unit length, unit area, or unit volume of a conductor is known as charge density. In other words, it shows the amount of charge that is held in a certain field. It determines how the charge is distributed and can be either positive or negative.
We encounter electric charge density when measuring electric fields from different continuous charge distributions including linear, surface, and volume. We must also take charge density into account when analyzing current electricity. We must first comprehend this concept of density in order to comprehend charge density. The definition of density for a thing is its mass per unit volume.
Size and charge density are inversely correlated, meaning that the smaller the size, the higher the charge density. This implies that Cl has a smaller volume and a higher charge density.

Its Na20
the formula for sodium oxide
Answer:
The answer to your question is remplacement double
Explanation:
Data
Lead (II) nitrate = Pb(NO₃)₂
Potassium iodide = KI
Process
1.- Write the balanced chemical reaction
Pb(NO₃)₂ + 2KI ⇒ PbI₂ + 2KNO₃
2.- Conclusion
This is a remplacement double reaction because there are two reactants that interchange cations and the products are a combination of the reactants.
