Chlorine gas can be produced in the laboratory by the following reaction.
$K_{2}C{r}_2{O}_7+14HCl\to 2KCl+2CrC{l}_3+7H_{2}O+3C{l}_2$ 
If 75 g sample of  $K_{2}C{r}_2{O}_7,$  with 98% purity is allowed to react with 365 ml of HCI solution having density of 1.2 g/ml and containing 28% HCI by mass, 'x'g of chlorine is produced. The value of 'x' is (Atomic weights of K=39, Cr =52, O = 16, 
Cl =35.5, H =1 )
