29 gm/ 22 liters X 1 liter/1000cc X (100cmx100cmx100cm)/1 liter
= (29 X 1 X 1000000) / (22 X 1000)
29000/22 = 1318 grams (rounded)

29gm/22liter x 1 liter/10^3 cc x (10^2 cm/m)^3 =
(29/22)gm/liter x 1 liter/10^3 cc x 10^6 cc/m^3 =
29/22 x 10^3 gm/m^3
This is the exact answer. Divide 29/22 and you have it to whatever decimal place you wish

set up a proportion
22000/29=1000000/x
22000x=29000000
x=1318.181818
