An environment  chemist needs a carbonate buffer of `pH=10` to study the effects of the acidification of limestones rich solis.How many grams of `Na_(2)CO_(3)` must be  added to `1.5L` of freshly prepared `0.2M NaHCO_(3)` to make the buffer.? For `H_(2)CO_(3),K_(a_(1))=4.7xx10^(-7),K_(a_(2))=4.7xx10^(-11)`
