Plz help with last two questions!!
Results Salt Concentration values for the unknown solutions (12 pts for the table) Unknown Solution Salt Concentration from Salt Concentration from density valu 2.14 4, o84 6.230 conductance value 4.516 Show the calculation for the salt concentration of Solution A from the density value. = 2.147, Show the calculation for the salt concentration of Solution A from the conductance 3o 343 0343 Which measurement (density or conductance) do you believe gives a more accurate method to determine the salt concentration of a solution? Explain your choice. (3 pts) Do you expect the conductance in water to be greater than or less than the conductance in the salt solutions? Explain your choice. (3 pts)

Explanation / Answer

3)

conductivity measurement is more accurate than density measurement

Reason: Density measurement will be more affected by small errors and calculating accurate mass and volume is difficult to calculate the concentration

Conductivity refers to the capability of passing the electrical flow. Since the salts, will dissociate into ions in water, this will increase the condictivity by making it easy for the passage of electrical flow.

Hence the conductance in water is greater in salt solution
