A label on a 500ml Dettol bottle,indicated chloroxylenol is 4.8g/100ml.his many molecules of chloroxylenol are in 25cm3of dettol?
25 cm^3 = 25 mL
4.8 g in 100 mL is 1.2 g in 25 mL
so how many grams is a mol? Google says
average for C8H9ClO is 156.7 g/mol
so
(1.2 g/156.7 g/mol)(6.02*10^23 molecules/mol)
= .0461 * 10^23
= 4.61 + 10^21 molecules
