Answer:
The stack would be 5.002 × 10⁷ inches high.
Explanation:
1 mole of ice cubes contains 6.022 × 10²³ cubes,
1 ice cube has a volume of 1 in³
This translates to a total volume of 6.022 × 10²³ in³
If we call the height of the stack of ice cubes we're about to produce H
The volume of ice cubes we have will take up a volume of [(3 × 10⁶)mi² × H]
Hence, we convert this area of land to in²
3 × 10⁶ mi² = 1.204 × 10¹⁶ in²
Therefore
6.022 × 10²³ = 1.204 × 10¹⁶ × H
H = (6.022 × 10²³)/(1.204 × 10¹⁶) = 5.002 × 10⁷ inches.
Answer:
When making ice cream, you're using physical changes. When you shake your bag, you're freezing the milk, which means the water in it is turning from a liquid (water) into a solid (ice).
