Question

number of oxygen atom is 4.4 gram of carbon dioxide is approximately equals to​

Answer 1

Total Mass = 12 + 16 x 2 = 44 g

now mass of O2 = 32 / 44 = 8 / 11 g

hence n = 8 x 11 / 44 = 2 mol

therefore N = n x NA

N = 2 x 6.022 x 10 ' s power 23

N = 1.2044 x 10 's power 23 hi!!!!!!!!!!cheers
