He bought 5 bottles of perfume that weighed 1.2 oz each so they weighed 5*1.2 = <<5*1.2=6>>6 oz
2 bars of soap weighed 5 oz each so they weighed 2*5 = <<2*5=10>>10 oz
2 jars of jam weighed 8 oz each so they weighed 2*8 = <<8*2=16>>16 oz
The perfume is 6 oz, the soap is 10 oz and the jam is 16 oz for a total of 6+10+16 = <<6+10+16=32>>32 oz
16 oz is 1 pound, and he had 32 oz in products so he had 32/16 = <<32/16=2>>2 pounds of products
His suitcase weighed 5 pounds, and the chocolate weighed 4 pounds and the remaining products weighed 2 pounds so his suitcase weighed 5+4+2 = <<5+4+2=11>>11 pounds
