Question

must be the volume of water used for 20g

Answer 1

Answer:

must be the volume of water used for 20g

Answer 2

Explanation:

4.9g of sulfuric acid is

98

4.9

= 0.05mol,

The neutalization reaction can be written as

NaOH+H

2

SO

4

→Na

SO

+H

2

O

Change in Free Energy is given as

ΔG = -15.3kJ

Change in Enthalpyis given as

ΔH = -15.6kJ

So, we need 0.1mol of NaOH (4 grams) to neutralize 0.05mol of sulfuric acid

Then 20g/Qml = 4g/400ml

Q = 400 x 20 / 4 = 2000

So, we add the 20g of NaOH to make 2000ml or 2L of basic solution.
