The mole fraction of SiO₂ in the glass : = 0.482
Further explanation
The mole fraction shows the mole ratio of a substance to the mole of solution /mixture
Can be formulated :
xa = na/(na+nb)
Find the moles of each component
SiO₂ :
= 20 g : 60,08 g/mol
= 0.333
PbO :
= 80 : 223,2 g/mol
= 0.358
Mol total :
= 0.333 + 0.358
= 0.691
Mol fraction of SiO₂ :
= 0.333/0.691
= 0.482
