Question

Calculate the mass of co2 which contain the same number of molecules as are contained in 40g of oxygen​

Answer 1

molar wt of O2 molecule = 32g

and given wt is 40g

so no.of moles of Oxygen is =40/32=1.25..moles ........as no.of molecules of CO2 and Oxygen are same so moles should same for both.....So moles CO2 also should be 1.25

and molar wt of CO2 is 44g ..so given wt of CO2= no.of moles* molar wt = 1.25 * 44=

55g
