Question

A Freon leak in the air conditioning system of an old car releases 26 g of CF2Cl2 each month. How many moles of fluorine atoms does the car emit in 1.6 years? The molar mass of Freon CF2Cl2 is 120.91 g/mol. S S M NH RI 1111111 ER ISRI Solution map is NOT required. TEL taran SHI EL LA TELE

Answer 1

No. Of month in 1.6 year = 12*1.6=19.2 months.

In one month CF2Cl2 release =26g

19.2 months release =26*19.2=499.2g

No of moles od CF2Cl2 in 499.2g = 499.2/120.91 =4.13 moles of CF2Cl2

1 mole CF2Cl2 have 2 mole of fluorine

So 4.13 mole of CF2Cl2 have = 4.13*2=8.26 moles of fluorine
