Question

calculate the mass of Co2 and CaO obtained when 1.5 mole of co3 is heated​

Answer 1

hi buddy

i guess your question is wrong

the question must be

calculate the mass of Co2 and CaO obtained when 1.5 mole of caco3 is heated​

as cao and co2 is npt obtained from co3

here is your answer

CaCO3----heat----> CaO+ CO2

then 1 mole of CaCO3 produces 1 mole of CO2 and 1 mole of CaO

mass of 1.5 mole of caco3= mass of 1 mole of caco3*1.5=150 gm

then 1.5 mole of CaCO3 produces 1.5 mole of CO2 and 1.5 mole of CaO

mass of CaO produced= 1.5*56=84 gm

mass of co2 produced= 1.5*44=66 gm
