4g equimolar mixture of NaOH and Na2CO3 contains x g of NaOH

Question

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 40

Mass of Na₂CO₃ = y

Moles of Na₂CO₃ = y 106

x 40 = y 106

x + y = 4

x = 1.1, y = 2.9

x = 1.1 1 (nearest integer)...
