Question

find the volume of co2 at stp whose wt is 11 g.

Answer 1

1mol CO2= 44g CO2 = 22.4L CO2 ( at STP)
then 11g CO2 = 1/4mol CO2 = 22.4/4L CO2
=5.6L CO2 (at STP)

Answer 2

At.wt of CO2 = 44g



At STP its volume is 22.4 Litre
so
44g---22.4 litre
11g ---- ?
Therefore
$(11 \times 22.4 )\div 44 = 5.6$
