Answer:
2.173 moles of ethanol is presented in a 100.0g sample of ethanol .
Explanation:
The amount of substance that contains as many Particles as there are atoms in exactly 12g of carbon- '12 isotope is called 1 mole '= 46 u.
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
