Question
Describe how to determine the density of an unknown liquid. If you determined that it has a density of 1.275 g/mL, what was its specific gravity? (assume water has a density of 1g/mL.) To measure the volume of a small non-uniform piece of an unknown metal, you fill a graduated cylinder with a small amount of water, and carefully place the metal into the cylinder. Before the metal was added, the cylinder had 6.87 mL of water. After you added the metal, the water line was at 11.46 mL. You then notice small bubbles on the metal piece. Will the density you calculate using the change in volume be too big or too small? Explain how you can tell.Explanation / Answer
Q3
a)
how to determine liquid density.
Simply:
1) weight your flask in the analytical balance, mark the weigth as "Mass of Flask"
2) fill it with 100 mL of liquid
3) weigh your flaks + liquid, marka s "mass of flask + mass of liquid"
4) calculate mass of liquid....
5) D = mass / volume
b)
D = 1.275 g/mL
find specifig gravity
reacall that
S.G. = Density of liquid / Density of water = 1.275/1 = 1.275 (no units!)
