Question

the number of oxygen atom is 1 atom of carbon dioxide is equal to that is Avagodro's number of carbon atoms (Nⁿ)+2xn of oxygen atoms​

Answer 1

★Any Query Then Ask It★

molar mass of CO2= 12 + 16 x 2 = 44g

44g of CO2 gives 1 mol of CO2

88g of CO2 gives 2 mol of CO2

1 mol of CO2 has 2 mol of O2

2 mol of Co2 has 4 mol of O2

So,

number of atoms = no. of moles x Avogadro's number = 4 x 6.023 x 10 ^ 23

Answer 2
