Question
Be sure to answer all parts. An empty Erlenmeyer flask weighs 241.3 g. When filled with water (d = 1.00 g/cm^3), the flask and its contents weigh 403.7 g. What is the volume of water in the flask? Enter your answer in scientific notation. How much does the flask weigh when filled with the same volume of chloroform (d = 1.48 g/cm^3)? Enter your answer in the provided box. An empty vial weighs 58.99 g. If the vial weighs 224.11 g when filled with liquid mercury (d = 13.53 g/cm^3), what volume of mercury is in the vial? Enter your answer in the provided box. An empty vial weighs 60.02 g. The vial weighs 377.37 g when filled with liquid mercury (d = 13.53 g/cm^3). How much would the vial weigh if it were filled with the same volume of water (d = 0.997 g/cm^3 at 25degreeC)?Explanation / Answer
Q1)
a) Weight of empty flask = 241.3 gms
Weight of water filled flask = 403.7 gms
Weight of water filled = 403.7 - 241.3 = 162.4 gms
Density of water = 1 gm/ml
Hence volume of water filled = 162.4 ml
Answer in scientific notation is 1.624 * 10^(2) ml
b) Weight of chloroform filled = Weight of empty flask + density of chloroform * volume
=> 241.3 + 1.48 * 162.4
=> 481.7
Q2)
Volume of mercury filled = (Weight of filled flask - Weight of empty flask)/density of mercury
=> (224.11 - 58.99)/13.53
=> 12.203 cm^3
Q2)
Volume of mercury filled = (Weight of filled flask - Weight of empty flask)/density of mercury
=> (377.37 - 60.02)/13.53
=> 23.455 cm^3
Weight of flask with new liquid = weight of empty flask + density(new) * volume
=> 60.02 + 0.997 * 23.455
=> 83.404 gms
