1. The mass of the air, given the data is 85.88 Kg
2. The weight of the air is 841.624 N
3. The mass of an equal volume of water is 67338 Kg
4. The weight of an equal volume of water is 659912.4 Kg
5. The volume of water that would have a mass equal to the mass of air in the room is 8.588×10⁻² m³
<h3>How to determine the volume of the air</h3>
We shall determine the volume of the air in the room by finding the volume of the room.
Volume of air = volume of room
Volume of air = 4.3 × 5.4 × 2.9
Volume of air = 67.338 m³
<h3>1. How to determine the mass of the air</h3>
- Volume of air = 67.338 m³
- Density of air = 1.2754 kg/m³
- Mass of air = ?
Density = mass / volume
Cross multiply
Mass = Density × volume
Mass of air = 1.2754 × 67.338
Mass of air = 85.88 Kg
<h3>2. How to determine the weight of the air</h3>
- Mass of air (m) = 85.88 Kg
- Acceleration due to gravity (g) = 9.8 m/s²
- Weight of air (W) = ?
W = mg
W = 85.88 × 9.8
Weight of air = 841.624 N
<h3>3. How to determine the mass of equal volume of water</h3>
- Volume of air = 67.338 m³
- Volume of water = Volume of air = 67.338 m³
- Density of water = 1000 kg/m³
- Mass of water = ?
Density = mass / volume
Cross multiply
Mass = Density × volume
Mass of water = 1000 × 67.338
Mass of water = 67338 Kg
<h3>4. How to determine the weight of equal volume of water</h3>
- Mass of water = 67338 Kg
- Acceleration due to gravity (g) = 9.8 m/s²
- Weight of water (W) = ?
W = mg
W = 67338 × 9.8
Weight of air = 659912.4 Kg
<h3>5. How to determine the volume of water with equal mass of air </h3>
- Mass of air = 85.88 Kg
- Mass of water = Mass of air = 85.88 Kg
- Density of water = 1000 kg/m³
- Volume of water = ?
Volume = mass / density
Volume of water = 85.88 / 1000
Volume of water = 8.588×10⁻² m³
