How many grams of carbon disulfide will react with 2.14 moles of oxygen
MAXImum [283]
Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂

For every mole of CS₂, 3 moles of Oxygen formed. 
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol

Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713        [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g

In short, Your Final Answer would be: 54.21 Grams

Hope this helps!
