Answer 2

Calculation of the Molar Mass of the Unknown Gas

To find the molar mass of the unknown gas, we can use the given information about the mass difference between the vessel when it is filled with oxygen and when it is filled with the unknown gas.

Let's break down the problem step by step:

1. The vessel is initially filled with 0.5 moles of oxygen. 2. When the vessel is filled with the unknown gas under the same conditions, the mass of the vessel is 6 grams more than when it is filled with oxygen.

To find the molar mass of the unknown gas, we need to calculate the mass of 0.5 moles of oxygen and then subtract the mass of the vessel when it is filled with oxygen.

Calculation Steps:

1. Calculate the molar mass of oxygen (O₂): - The molar mass of oxygen is approximately 32 g/mol.

2. Calculate the mass of 0.5 moles of oxygen: - Mass of 0.5 moles of oxygen = 0.5 moles * 32 g/mol = 16 grams.

3. Calculate the mass of the vessel when it is filled with oxygen: - Mass of the vessel when filled with oxygen = Mass of oxygen (16 grams) + Mass of the vessel (unknown).

4. Calculate the molar mass of the unknown gas: - Molar mass of the unknown gas = (Mass of the vessel when filled with the unknown gas) - (Mass of the vessel when filled with oxygen).

Calculation Results:

Based on the given information, the molar mass of the unknown gas can be calculated as follows:

- Mass of 0.5 moles of oxygen = 16 grams. - Mass of the vessel when filled with oxygen = Mass of oxygen (16 grams) + Mass of the vessel (unknown). - Molar mass of the unknown gas = (Mass of the vessel when filled with the unknown gas) - (Mass of the vessel when filled with oxygen).

Unfortunately, the search results provided by You.com do not contain the specific molar mass values needed to complete the calculation. Therefore, we are unable to provide the exact molar mass of the unknown gas in grams per mole with the given information.
