Determine the apparent molar mass of a mixture of oxygen (2 kg)with nitrogen (3kg),kg/mol 0.295 294,7 0,0295 2.947 29.47

To determine the apparent molar mass of a mixture of oxygen and nitrogen, we need to calculate the total mass of the mixture and the total number of moles of each gas.<br /><br />Given information:<br />- Mass of oxygen: 2 kg<br />- Mass of nitrogen: 3 kg<br /><br />Step 1: Calculate the molar mass of oxygen and nitrogen.<br />- Molar mass of oxygen (O2) = 32 g/mol<br />- Molar mass of nitrogen (N2) = 28 g/mol<br /><br />Step 2: Calculate the number of moles of oxygen and nitrogen.<br />- Number of moles of oxygen = 2 kg / 32 g/mol = 62.5 mol<br />- Number of moles of nitrogen = 3 kg / 28 g/mol = 107.1 mol<br /><br />Step 3: Calculate the total mass of the mixture.<br />- Total mass of the mixture = 2 kg + 3 kg = 5 kg<br /><br />Step 4: Calculate the total number of moles of the mixture.<br />- Total number of moles = 62.5 mol + 107.1 mol = 169.6 mol<br /><br />Step 5: Calculate the apparent molar mass of the mixture.<br />- Apparent molar mass = Total mass of the mixture / Total number of moles<br />- Apparent molar mass = 5 kg / 169.6 mol = 0.0295 kg/mol<br /><br />Therefore, the correct answer is 0.0295 kg/mol.
