The density of aluminum is 2.7 g/cm³. What is the mass of a piece of aluminum foil which is 10.0 cm by 5.0 cm by 0.0018 cm thick?

Question

Quizplus · Accepted Answer

The volume of the aluminum foil can be found by multiplying the length, width, and thickness:
V = 10.0 cm x 5.0 cm x 0.0018 cm = 0.09 cm^3

The mass of the aluminum foil can be found by multiplying the volume by the density:
m = V x d = 0.09 cm^3 x 2.7 g/cm^3 = 0.243 g

Therefore, the answer is C, 0.24 g (rounded to two significant figures).
