The empirical formula for 200 grams of an organic sample which contains carbon,hydrogen, and oxygen is C3H6O
Answer:
B. Conclusions are based on observations
Explanation:
Given:
n = 12 moles of oxygen
T = 273 K, temperature
p = 75 kPa, pressure
Use the ideal gas law, given by

where
V = volume
R = 8.3145 J/(mol-K), the gas constant
Therefore,

Answer: 0.363 m³
