Question

no of atoms in 22g of co2

Answer 1

HELLO MR.


HERE IS YOUR ANSWER


relative molevular mass of co2 is 44.(O=16,C=12).so the number of atoms in 44g is 6.022×10^23(avegadro constant).therefore the number of carbon atoms in 22g is6.022×10^23/2.as in one atom there is only one atom of carbon


THANK YOU

Answer 2

Answer:

3.011 * 10^23

Explanation:

moles of co2= given mass/moler mass of co2

moles of co2= 22/ 12 + 16(2)

moles of co2                       =0.5

no. of atom of co2= no. of mole * avegdros constant

                             =0.5* 6.022 *10^23

                            =3.011 * 10^23
