If the person is unconscious but still breathing, put them into the recovery position with their head lower than their body and call an ambulance immediately. Continue watching the patient to ensure they don't stop breathing and continue to breathe normally.
I'll assume that the lung volume is 5.30 L. 1L= 1dm 3 5.30dm 3 x ( 1m/ 10 dm )3 x ( 1.5 ug pb / m 3) x ( 1 g pb /1 x 10 6 ug pb ) x ( 1 mole pb /207.2 g pb) x( 6.02 x 10 23 pb atoms / 1 mole pb) =2.3 x 10 13 pb atoms
