Answer:
178.5g of NaCl is the maximum amount that can be dissolved
Explanation:
Solubility is defined as the maximum amount of solute that can be dissolved in aAt 20°C, the solubility of NaCl is 35.7g per 100g of water at 20°C. That means the maximum amount that can be dissolved of NaCl is:
500g water * (35.7g NaCl / 100g water) =
<h3>178.5g of NaCl is the maximum amount that can be dissolved</h3>

Mass of ZnO added=1.765 g
<h3>
Further explanation:</h3>
Given
30gms of 10%ZnO(Zinc oxide)
15% ZnO
Required
mass of ZnO added
Solution
Amount of ZnO in 30 gms of 10% ZnO =3 gms
For 15% ZnO : x= ZnO added
New solution = 30+x = 15%, so the equation :
