Answer:
1.53 L
Explanation:
Step 1: Given data
- Mass of oxygen (m): 11.2 g
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Calculate the moles (n) corresponding to 11.2 g of oxygen
The molar mass of oxygen is 32.00 g/mol.
11.2 g × (1 mol/32.00 g) = 0.350 mol
Step 3: Calculate the volume of oxygen
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 0.350 mol × (0.0821 atm.L/mol.K) × 415 K / 7.78 atm
V = 1.53 L
Answer:
Both apply to a certain region
Choice C is correct
Explanation:
Weather refers to the atmospheric conditions of a given place over a short period of time, like a day.
On the other hand, Climate refers to the average climatic conditions of a particular region measured over a long period of time.
Both weather and climate apply to a certain region.
Answer:
