High-Strength Ceramic Materials Production Calculation
Chemical Equation
SiO₂ + 3C → SiC + 2CO
Calculation
Given data:Mass of SiO₂ react = 352 g
Mass of SiC formed = ?
Solution:Number of moles of SiO₂:
Number of moles = mass / molar mass
Number of moles = 352 g / 60.08 g/mol
Number of moles = 5.86 mol
Now, we will compare the moles of SiO₂ with SiC from the balanced chemical equation:
SiO₂ : SiC
1 : 1
5.86 : 5.86
Mass of SiC:
Mass = number of moles × molar mass
Mass = 5.86 mol × 40.11 g
Mass = 235 g
Therefore, the mass of silicon carbide produced from the reaction of 352 g of silicon dioxide is 235 g.
