Verified Solution • 2025–26 Session moderate

4g equimolar mixture of NaOH and Na₂CO₃ contains x g of NaOH and y g of Na₂CO₃. The value of x is ____________ g. (Nearest integer)

Accepted Answer

Mass of NaOH = x

Moles of NaOH =

{x \over {40}}

Mass of Na₂CO₃ = y

Moles of Na₂CO₃ =

{y \over {106}}

{x \over {40}} = {y \over {106}}

x + y = 4

x = 1.1, y = 2.9

x = 1.1

\approx

1 (nearest integer)
