Answer:

0.00182 cm

Explanation:

Area of the aluminum foil = 22.86 cm ×22.86 cm = 522.58 cm^2

Density = mass/area × thickness

Density × area × thickness = mass

Thickness = mass/ Density × area

Thickness = 2.568 g/2.70 g/cm^3 × 522.58 cm^2

Thickness= 0.00182 cm

Is apple juice a homogeneous mixture or a heterogeneous mixture
Solnce55 [7]

If you mean the industrialized apple juice then yes. Even though there are several different compounds and some of them aren't actually dissolved in the liquid, since you can't actually distinguish between them using only your eyes and they do no separate naturally it is actually a homogeneous mixture.
