5.3 % (w/v) Na_(2)CO_(3) solution and 6.3 % (w/v) H_(2)C_(2)O_(4).2H_(2)O solution have same

Answer»

molality
MOLARITY
normality
mole fraction.

Solution :`M_(Na_2CO_3) = (5.3)/(106) xx (1000)/(100) = (1)/(2)=0.5`
`N_(Na_2CO_3) = 0.5 xx 2 =1.0`
`MH_(2)C_(2)O_(4).2H_(2)O = (6.3)/(126) xx (1000)/(100) = 1/2 =0.5`
`NH_(2)C_(2)O_(4).2H_(2)O= 0.5 xx 2=1`Both solutions have same molartiy and normality .
