Calculate the mass % of `Na_(2)CO_(3)` in a mixture having mass 206 gm which produced 24 litre of `CO_(2)` at 1 atm pressure & 300 K wich axcess of HCl. [R=0.08 atm lit/mok K]

Calcualte the mass % of Na_(2)CO_(3) in a mixture having mass 206 gm which produces 24 litre of CO_(2) at 1 atm pressure and 300K with excess of HCL. [R = 0.08 atm lit/mol K]

Calculate maximum mass of CaCl_(2) produced when 2.4 xx 10^(24) atoms is taken with 96 litre of Cl_(2) gas at 380 mm pressure and at 27^(@) C. [R : 0.08 atm L/mol-K & N_(A) = 6 xx 10^(23) ]

20 g mixture of Na_(2)CO_(3) and CaCO_(3) is gently heated. On heating this sample produces 2.24 litre of CO_(2) at STP. Calculate the % weight of Na_(2)CO_(3) in that sample.
