One way of obtaining pure sodium carbonate is through the decomposition of the mineral trona, na3(co3)(hco3)·2h2o. 2na3(co3)(hco3)·2h2o(s) → 3na2co3(s) + co2( g. + 5h2o( g. when 1.00 metric ton (1.00 × 103 kg) of trona is decomposed, 0.650 metric ton of na2co3 is recovered. what is the percent yield of this reaction?
