The mass of silicon, Si produced from the reaction is 329.41 g
SiCl₄ + 2Mg —> 2MgCl₂ + Si
Molar mass of SiCl₄ = 28 + (35.5×4) = 170 g/mol
Mass of SiCl₄ from the balanced equation = 1 × 170 = 170 g
Molar mass of Si = 28 g/mol
Mass of Si from the balanced equation = 1 × 28 = 28 g
From the balanced equation above,
170 g of SiCl₄ reacted to produce 28 g of Si.
From the balanced equation above,
170 g of SiCl₄ reacted to produce 28 g of Si.
Therefore,
2 Kg (i.e 2000 g) of SiCl₄ will react to produce = (2000 × 28) / 170 = 329.41 g of Si
Thus, 329.41 g of Si were obtained from the reaction
