Question

no. of molecule in 11200 ml of CO2

Answer 1

Answer:

= 3.011 × 10²³

Explanation:

as we know,

Standard volume= 22.4 L

it means that 1 mole of any atom,molecule or ion occupies 22.4 L of volume at STP ( standard temperature and pressure)

therefore,

1 mole of Co2 = 22.4 L

given volume = 11200 ml

or

= 11.2 L (1000ml = 1L)

No. of moles = given volume/standard

volume

= 11.2/22.4

= 0.5

no.of molecules =

no.of moles × Avogadro No.

= 0.5×6.022×10²³

= 3.011 × 10²³
