Question
2. Assume that you did not rinse the graduated cylinder with your unknown before filling it with 24 mL of the salt solution in Part IIA. The graduated cylinder was only rinsed with DI water. If the true density of your salt solution is 1.21 g/cm3, will your calculated density of the salt solution be lesser than, greater than, or equal to 1.21 g/cm3? Explain why and be specific. (density of water at 25 'C is 1.00 g/om) 3. Assume that a few drops of water were on the outside of your graduated cylinder during the procedure for Part IIA. The water remained on the graduated cylinder each time the mass was measured. Will your calculated density be too low, too high, or unaffected by this? Explain why and be specific. hoc a density of 0,786 g/cm3. How many pounExplanation / Answer
2. As some portion of distilled water is remained inside of the graduated cylinder and as the density of water is less than that of the salt solution thus mass per unit volume will decrease due to the remaining portion of water in the inside of cylinder as volume will increase in this case and hence there'll be a little decrease in the density of the solution from 1.21g/cm³.
.
3. Density is equal to mass per unit volume i.e density is directly proportional to the mass. Now here due to those few drops of water the mass of salt solution will be a little bit higher so density will also be a little bit more than 1.21 g/cm³.
