Answer:
Explanation:
equimolar mixtures means equal moles
suppose grams of na2co3 = x
grams of nahco3 should be 1-x
valency factor of na2co3 = 2
valency factor of nahco3 = 1
moles of na2co3= moles of nahco3
x/142 = 1-x/ 84
84x = 142 - 142x
226x = 142
x=0.628
equivalent of na2co3 = 88
equivalent of nahco3 = 44
equivalent of na2co3 + equivalent of nahco3 = 0.1n
132 = 0.1 n
1320 ml = volume
