Answer:
Oxygen can get into the water in several ways: Oxygen from the atmosphere dissolves and mixes into the water's surface. Algae and underwater grasses release oxygen during photosynthesis. Water flows into the Bay from streams, rivers and the ocean.
Explanation:
From the ideal gas law, PV = nRT, we can rearrange the equation to solve for T given the other parameters.
T = PV/nR
where P = 0.878 atm, V = 1.20 L, n = 0.0470 moles, and R = 0.082057 L•atm/mol•K. Plugging in our values, we obtain the temperature in Kelvin:
T = (0.878 atm)(1.20 L)/(0.0470 mol)(0.082057 L•atm/mol•K)
T = 273 K
So, the second answer choice would be correct.
