S u b t r a c t i n g space t h e space t w o space e q u a t i o n space w e space g e t space

minus 1 half M subscript e q end subscript space o f space N a subscript 2 C O subscript 3 space equals space minus 5.5

S o comma space M subscript e q end subscript space o f space N a subscript 2 C O subscript 3 space equals space 11
space space space space space space M subscript e q end subscript space o f space N a O H equals 14

H e n c e space w e i g h t space o f space space N a subscript 2 C O subscript 3 space p e r space l i t r e space equals fraction numerator 11 cross times 10 to the power of negative 3 end exponent over denominator 0.025 end fraction cross times 106 over 2 equals 23.32 space g L to the power of negative 1 end exponent
