chloride in water and measure the conductivity with a calibrated conductivity meter so you can verify the molarity. The first solution you will need to produce is 100.0 mL of 1.50 M CaCl2. Once you make your first solution, you nee to make a second solution through dilution of 100.0 mL of 0.250 M CaCl2. ​

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

idk i'm not smart
