Answer 2

To determine the mass (m) and volume (V) of sulfur dioxide (SO2) when you have 2 moles of it, you need to use its molar mass and the ideal gas law.

1. Molar Mass of SO2: The molar mass of SO2 is calculated by adding the atomic masses of its constituent elements:

• Sulfur (S): Atomic mass = 32.07 g/mol
• Oxygen (O): Atomic mass = 16.00 g/mol (there are 2 oxygen atoms in SO2)

Molar mass of SO2 = (1 × 32.07 g/mol) + (2 × 16.00 g/mol) = 64.07 g/mol

2. Mass (m) of 2 Moles of SO2: Given that you have 2 moles of SO2, you can calculate the mass using the molar mass: Mass (m) = Moles (n) × Molar Mass Mass (m) = 2 moles × 64.07 g/mol = 128.14 grams

So, you have 128.14 grams of sulfur dioxide.

3. Volume (V) of 2 Moles of SO2: To calculate the volume, you can use the ideal gas law, which relates moles, pressure, volume, and temperature of a gas. The ideal gas law is expressed as:

PV = nRT

Where:

• P is the pressure (which is not given)
• V is the volume
• n is the number of moles (given as 2 moles)
• R is the ideal gas constant (8.314 J/(mol·K))
• T is the temperature in Kelvin (which is not given)

Since pressure and temperature are not provided, you cannot calculate the volume (V) without this information. To calculate the volume, you would need both the pressure and temperature of the gas in addition to the number of moles.
