Answer:
There will react 485.76 grams of O2
Explanation:
Step 1: Data given
Mass of CS2 = 385 grams
Molar mass CS2 = 76.14 g/mol
Molar mass of O2 = 32 g/mol
Step 2: The balanced equation
CS2(s) + 3O2(g) → CO2(g) + 2SO2(g)
Step 3: Calculate moles of CS2
Moles CS2 = mass CS2 / molar mass CS2
Moles CS2 = 385 grams / 76.14 g/mol
Moles CS2 = 5.06 moles
Step 4: Calculate moles of O2
For 1 mol of CS2 we need 3 moles of O2 to produce 1 mol of CO2 and 2 moles of SO2
For 5.06 moles of CS2, we need 3* 5.06 = 15.18 moles of O2
Step 5: Calculate mass of O2
Mass O2 = moles O2 * molar mass O2
Mass O2 = 15.18 moles * 32.00 g/mol
Mass O2 = 485.76 grams O2
There will react 485.76 grams of O2
