Answer :

Final answer:

To find the number of moles of O2 gas in the container, use the Ideal Gas Law equation PV = nRT. Substitute the given values to calculate the number of moles.

Explanation:

To determine the number of moles of O2 gas in the given container, we can use the Ideal Gas Law equation: PV = nRT. Here, P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin. Rearranging the equation, we have n = PV / RT. We can substitute the given values into the equation to find the number of moles of O2 gas in the container.

P = 1.3 atm

V = 3700 mL = 3.7 L

T = 33°C = 33 + 273 = 306 K

R = 0.0821 L·atm/mol·K

n = (1.3 atm) * (3.7 L) / (0.0821 L·atm/mol·K * 306 K) = 0.178 mol

Therefore, there are 0.178 moles of O2 gas in the 3700 mL container.
