Question #e96d5

1 Answer

0.932×105

Explanation:

It's so easy to understand.

The only thing we have to know is that 1 mol of any gas has a volume of 24.04 L at NTP (Normal Temperature and Pressure)

Here the volume is given as 2.24 mL.

                     1 L = 1000 mL

Hence 1 mL=103 L

2.24 mL=2.24×103 L

24.04 L of CO2=1 mol of CO2 (at NTP only)

2.24×103 L CO2×1 mol CO224.04 L CO2=9.32×105 mol CO2

Therefore 2.24 mL CO2 at NTP contains 0.932×105 mol CO2.
