1.	The no of oxygen atom in 4.4g of co2 is approximately
Answer» Moles of\xa0CO2\u200b= 4.4\u200b/ 44 =0.1\xa0moles∴\xa0Number of molecules of\xa0CO2\u200b=0.1×6.022×1023=6.022×1022\xa0moleculesBut\xa01\xa0molecule of\xa0CO2\u200b\xa0contains\xa02\xa0oxygen atoms.∴\xa0Number of oxygen atoms=2×6.022×1022=12.044×1022\xa0atoms=1.2×1023\xa0atoms
