Gallium hydroxide reacts with sodium sulfite to yield gallium sulfite and sodium hydroxide. reacting 2.29 moles of sodium sulfite will require moles of gallium hydroxide.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. # of neutrons = Mass Number - Number of Protons To be able to apply this formula, refer to the atomic number and atomic weight of the elements. These two are listed in the Periodic Table of Elements.
