Answer:
The correct answer is option B.
Explanation:
Pressure of the gas = P = 101 kPa = 0.9968 atm
Volume of the gas = V = 4.5 L
Temperature of the gas = T = 300°C = 573.15 K
Moles of sulfur dioxide = n
n = 0.09533 mol
According to reaction , 1 mol sulfur dioxide is obtained from 1 mol of sulfur.
Then 0.09533 mol will be obtained from:
Mass of 0.09533 moles of sulfur = 0.09533 mol × 32 g/mol= 3.07 g
