Answer: There are [tex]0.052\times 10^{23}[/tex] oxide ions
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{0.55gg}{64g/mol}=0.0086moles[/tex]
1 mole of TiO contains = [tex]6.023\times 10^{23}[/tex] oxide ions
Thus 0.0086 moles of TiO contains = [tex]\frac{6.023\times 10^{23}}{1}\times 0.0086=0.052\times 10^{23}[/tex] oxide ions
There are [tex]0.052\times 10^{23}[/tex] oxide ions
