Answer 2

Problem:

In a given scenario, we have the following quantities of different substances: - Freshwater: 249 g - Saltwater: 256 g - Freshwater ice: 229 g - Saltwater ice: 246 g - Freshly fallen snow: 18 g - Packed snow: 108 g

We need to perform two actions: 1. Calculate the total mass of water (freshwater and saltwater) and the total mass of ice (freshwater ice and saltwater ice). 2. Determine the difference between the mass of freshly fallen snow and packed snow.

Solution:

1. To calculate the total mass of water, we add the mass of freshwater and saltwater: - Freshwater mass: 249 g - Saltwater mass: 256 g - Total mass of water = Freshwater mass + Saltwater mass = 249 g + 256 g = 505 g.

To calculate the total mass of ice, we add the mass of freshwater ice and saltwater ice: - Freshwater ice mass: 229 g - Saltwater ice mass: 246 g - Total mass of ice = Freshwater ice mass + Saltwater ice mass = 229 g + 246 g = 475 g.

2. To determine the difference between the mass of freshly fallen snow and packed snow, we subtract the mass of packed snow from the mass of freshly fallen snow: - Mass of freshly fallen snow: 18 g - Mass of packed snow: 108 g - Difference = Mass of freshly fallen snow - Mass of packed snow = 18 g - 108 g = -90 g.

The negative value indicates that the mass of packed snow is greater than the mass of freshly fallen snow by 90 grams.

Answer:

1. The total mass of water (freshwater and saltwater) is 505 grams. 2. The total mass of ice (freshwater ice and saltwater ice) is 475 grams. 3. The difference between the mass of freshly fallen snow and packed snow is -90 grams.
