Answer:
Put it on a ship or an aerogel
Explanation:
You can use an aerogel, a synthetic porous ultralight material. The aerogel can support a mass many times greater than their own.
Even simpler, you can put the object on board a ship. The ship has a smaller density than water, making it float in water.
Is this all you need or more ?
Equal volumes of equal concentrations of strong acid and strong base are mixed. Because the volumes and molarities are equal, the number of mole NaOH and HCl are equal.
From reaction
HCl + NaOH ---> NaCl +H2O
we can see that if number of moles HCl and NaOH are equal, they will react completely, and no acid or base is going to be in solution anymore.
So, pH=7.
