Answer 2

Calculating the Mass of Air Inhaled in 1 Hour

To calculate the mass of air inhaled in 1 hour, we can use the following steps:

1. Calculate the volume of air inhaled in 1 minute. 2. Convert the volume of air inhaled in 1 minute to liters. 3. Calculate the mass of air inhaled in 1 minute. 4. Convert the mass of air inhaled in 1 minute to kilograms. 5. Multiply the mass of air inhaled in 1 minute by 60 to find the mass of air inhaled in 1 hour.

Step 1: Calculate the Volume of Air Inhaled in 1 Minute

The volume of air inhaled in 1 minute can be calculated by multiplying the number of breaths per minute by the volume of air inhaled with each breath.

Given: - Number of breaths per minute = 15 - Volume of air inhaled with each breath = 1600 cm^3

The volume of air inhaled in 1 minute = 15 breaths/minute * 1600 cm^3/breath

Step 2: Convert the Volume of Air Inhaled in 1 Minute to Liters

To convert the volume of air from cubic centimeters to liters, we can use the conversion factor: 1 liter = 1000 cm^3.

Step 3: Calculate the Mass of Air Inhaled in 1 Minute

The mass of air inhaled in 1 minute can be calculated using the density of air, which is approximately 1.225 kg/m^3 at 0°C and 1 atmosphere of pressure.

Step 4: Convert the Mass of Air Inhaled in 1 Minute to Kilograms

After calculating the mass of air inhaled in 1 minute, we can convert it to kilograms for convenience.

Step 5: Multiply the Mass of Air Inhaled in 1 Minute by 60

To find the mass of air inhaled in 1 hour, we can simply multiply the mass of air inhaled in 1 minute by 60.

Let's proceed with the calculations.
