Answer:
It should be acetic acid.
Explanation:
When you have ionic bonds, the ionic bonds will always be water soluble; the polarity doesn't matter for this case.
Drying clothes is a physical change, because it is not permanent. The clothes could just be wettened again, therefore it is not a chemical change.

0.115 M means that 0.115 moles of KBr are contained in a volume of 1000 ml, therefore a volume of 350 ml will have (0.115 × 0.35) = 04025 moles
From the formula of molarity moles = molarity × volume in liters
1 mole of KBr is equivalent to 119 g
Therefore, the mass = 0.04025 × 119 g = 4.79 g
Equal is the answer
Hope this helps
