Question

number of molecules present in 11.2 l of co2 at stp

Answer 1

Answer:

No. of molecules=3.011×10^23.

Step-by-step explanation:

No.of moles=Given Volume/Molar Volume

nCO2=11.2L/22.4L.........(Since,22.4L is a constant value for Molar volume)

nCO2=1/2.

Now,

No. of molecules=No. of moles×NA(Avagadro's number)

No. of molecules=1/2×6.022×10^23

No. of molecules=3.011×10^23.

Thus, no. of molecules present in 11.2L of CO2 at STP is 3.011×10^23.
