A chemical reaction that has a positive g is best described as endergonic.
Answer:
a) Volume of vial= 9.626cm3
b) Mass of vial with water = 62.92 g
Explanation:
a) Mass of empty vial = 55.32 g
Mass of Vial + Hg = 185.56 g
Therefore,

Density of Hg = 13.53 g/cm3

b) Volume of water = volume of vial = 9.626 cm3
Density of water = 0.997 g/cm3

Formula:

Given:
Density=3.4
Volume=500.0
Plug them into the formula:
Final answer: 1700g
