An empty vial has a mass of 50.51 g.

(1) If the vial was filled with water (d = 0.997

g/cm³ at 25°C) and the mass of the filled vial was

111.9 g, calculate the volume (V) of water in the

vial.

a. [3 pts] V is calculated using the following

equation: V =

b. [7 pts] V =

(2) What would be the mass of the vial upon filling

it with the same volume (V) of an unknown

liquid (d = 12.1 g/cm³ at 25°C)?

a. [3 pts] The equation to calculate the mass of the

unknown liquid in the vial is

Unit =

b. [7 pts] The mass of the filled vial =

Unit =
