(1.7 x 104cm) 80.2 5. A metal d isk has a mass of 14.37 g. If the density of the metal is 4,93 g/em\' and the diameter of the disk is 8.00 cm, what is the thickness of the disk? 0.0580 cm) Instructor\'s Initials Lab 5 61

Solution

5. volume = mass / density

volume of disc = 14.37 / 4.93 = 2.9148 cm³

redius = diameter/2 = 8 / 2 = 4 cm

value of Pi = 3.14

formula for volume of disc(V) = r²h

h = r²/V

Substitute value

h = 2.9148 / 3.14 X 4² = 0.0580 cm

thickness of disc = 0.0580 cm
