Question

Calculate the mass of sodium sulphate formed when caustic soda reacts with king of chemicals (atomic masses of Na = 23 u 0= 16 H = 1 S= 32 u​

Answer 1

Answer:

Hi Friend,

Here is your answer........

Explanation:

The chemical formula of Sodium Sulphate is Na2SO4 and Caustic Soda is NaOH

Mass of 2 Sodium=23*2=46

Mass of sulphur=32

Mass of oxygen=16*4=64

Total mass of Sodium Sulphate

=46+32+64

=142u

ON THE OTHER SIDE,(in Caustic soda)

Mass of Sodium=23

Mass of oxygen=16

Mass of Hydrogen=1

Total mass of caustic soda

=23+16+1

=40u

At a result,

The total mass of the compound=Total mass of Sodium Sulphate + Total mass of Caustic Soda

=40+142

=182u

Hope it will be Helpful to you........
