Question

Calculate number of molecules present in 11.2 dm3 volume at stp

Answer 1

Answer:

1/2 moles are present in 11.2dm^3

number of moles = 11.2/ 22.4

= 1/2

In 1 mole 6.023*10^23 molecules are present

so in 1/2 moles 1/2 * 6.023*10^23 molecules are present .

11.2 dm ^3 volume at stp contain 3.011*10^23 molecules

Answer 2

Answer:

1/2 moles are present in 11.2dm^3

number of moles = 11.2/ 22.4= 1/2

In 1 mole 6.023*10^23 molecules are present

so in 1/2 moles 1/2 * 6.023*10^23 molecules are present .

11.2 dm ^3 volume at stp contain 3.011*10^23 molecules
