Answer:
6.9 g
Step-by-step explanation:
1. Use the Ideal Gas Law to find the <em>number of moles
</em>
pV = nRT Divide each side by RT
n = (pV)/(RT)
<em>Data:
</em>
p = 102 kPa
V = 6.0 L
R = 8.314 kPa·L·K⁻¹mol⁻¹
T = (37 + 273.15) K = 310.15 K
<em>Calculation:
</em>
n = (102 × 6.0)/(8.314 × 310.15)
n = 0.237 mol
2. Calculate the <em>mass of air
</em>
Mass of air = 0.237 mol × (29 g/1 mol)
Mass of air = 6.9 g

It's Co just look at the periodic table
Answer: amount = 2466.95L
Explanation:
given that the speed is = 1900./kmh i.e. 1hr/900km
distance = 1050km
the fuel burns at a rate of 74.4 L/min
therefore the amount of fuel that the jet consumes on a 1050.km becomes;
total fuel used = time × fuel burning rate
where time = distance / speed
∴ total fuel used (consumed) = time × fuel burning rate
total fuel consumed = (1050km × 1hr/1900km) × (60min/ 1hr × 74.4L/1min)
total fuel consumed = 2466.95L
A. When the substance is in its gaseous state.
<u>Explanation:</u>
When a substance is expanding against its constant volume and pressure, its temperature increases except when the substance is in gaseous state and not in liquid or solid state. So the internal energy increase in the system not only increases and maintaining the volume and pressure of the system remains constant in its gaseous phase. In the first law of Thermodynamics, it is used specifically that to especially in the case of gaseous system.
