Answer:
Vf = 1.22 mL
Explanation:
If we assume that the pressure is constant and the number of moles does not change, we can say that the volume of the gas is modified in a directly ratio, to the Absolute Temperature.
Let's convert the values:
91°C + 273 = 364K
0.9°C + 273 = 273.9K
Volume decreases if the temperature is decreases
Volume increases if the T° increases
V₁ / T₁ = V₂ / T₂ → 1.63mL /364K = V₂ / 273.9K
V₂ = (1.63mL /364K) . 273.9K → 1.22 mL
Answer:
The final volume of the oxygen gas is 1.23 mL
Explanation:
Step 1: Data given
Volume of the syringe = 1.63 mL = 0.00163 L
Initial temperature = 91.0°C = 364.15 K
Final temperature = 0.9 °C = 274.05 K
Step 2: Calculate the final volume
V1/T1 = V2/T2
⇒with V1 = the initial volume = 0.00163 L
⇒with T1 = the initial temperature = 364.15 K
⇒with V2 = the final volume = TO BE DETERMINED
⇒with T2 = the final temperature = 274.05 K
0.00163/364.15 = V2 / 274.05
V2 = 0.00123 L = 1.23 mL
The final volume of the oxygen gas is 1.23 mL
