Asked by Ujjwal Kumar | 5th Oct, 2010, 08:16: PM
Expert Answer:
Moles of O2=wt of O2/mol.wt of O2
=20/32
=.625 moles of O2
and the number of moles of O2 will be equal to the number of moles of CO2 as they contain same number of atoms as are with O2.
hence, number of moles of CO2 =.625
and we know that,
Number of moles=wt./mol.wt
molecular wt of CO2=12+2*16=44
.625=wt of CO2/44
wt of CO2=27.5 g.
