From the conversion table:
1 meter = 100 cm
Therefore, all you need to do to convert <span>0.0075 meters to centimeters is cross multiplication as follows:
</span>0.0075 meters = (<span>0.0075 x 100) / 1 = 0.75 cm</span>
PH=-lg[H⁺]
pH=-lg(1.0*10⁻¹¹)=11
pH=11
3 lithium ions bond to one nitrogen ion.
