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