How many moles of oxygen (O2) are present in 33. 6 L of the gas at 1 atm and 0°C? 1. 5 2 22. 4 32.
oee [108]

The number of moles of oxygen in the gas is 1.5 L.

The correct option is (A).

<h3>What are moles? </h3>

The mole is the International System of Units' foundation unit of material quantity.

Given,

The volume of gas is 33.6 L

Pressure is 1 atm.

Temperature is 0°C

Molar gas volume is 22.4 L

There is no temperature and pressure is 1 atm.

By formula of moles, volume is divided by molar mass

\bold{\dfrac{33.6}{22.4 } =1.5\; mole}

Thus, option A is correct. 1.5 L.

lubasha [3.4K]

Answer:

300000Pa or 3×10^5 Pa

Explanation:

Since the problem involves only two parameters of volume and pressure, the formula for Boyle's law is suitably used.

Using Boyle's law

P1V1 = P2V2

P1 is the initial pressure = 1.5×10^5Pa

V1 is the initial volume = 0.08m3

P2 is the final pressure (required)

V2 is the final volume = 0.04 m3

From the formula, P2 = P1V1/V2

P2 = 1.5×10^5 × 0.08 ÷ 0.04

= 300000Pa or 3×10^5 Pa.
