Question

a man was found to have 6 mmol/litre of lead in his blood, if 1000mmol =1 mol

and the man has 5 litres of blood in him. how many grams of lead will he have in his blood

Answer 1

n = m / M

m = n x M

M (Pb) = 207.2 g/mol

n (Pb) = 6 x 5 = 30 mmol / l = 0.03 mol/l

m (Pb) = 0.03 x 207.2 = 6.2 g
