Question
Estimate the weight (in pounds) oftwo large bottles of soda pop. Notethat 1 L of water has a mass of about1 kg. Use the fact that an objectweighing 2.2 lb has a mass of 1 kg.Find some bathroom scales andcheck your estimate.
Solution
Sure, let's break this down:
-
First, we need to estimate the volume of two large bottles of soda pop. A large bottle of soda typically contains 2 liters. So, two bottles would contain 4 liters.
-
Given that 1 liter of water has a mass of about 1 kg, we can assume that 4 liters of soda pop would have a mass of about 4 kg. This is because the density of soda pop is close to that of water.
-
We know that an object weighing 2.2 lb has a mass of 1 kg. Therefore, an object with a mass of 4 kg would weigh 4 * 2.2 lb = 8.8 lb.
-
To check this estimate, you could place the two bottles of soda pop on a bathroom scale and see if the weight is close to 8.8 lb. Keep in mind that this is an estimate, and the actual weight could be slightly more or less due to the sugar and other ingredients in the soda pop.
