Answer 1

Answer:

Explanation:

Since the water density is 1

Igm=1ml

So total mass is 500 + 20 + 30 = 550gm

Mass% of glucose =30/550

Mass% of salt =50/550

B) when sulphuric acid is added to acid then a compound is formed.

Because when it is added the acid is dissociated into ions so no mixture is formed
