If the coefficient of volume expansion of mercury is βhgβhgbeta_hg = 1.80×10−4 /k/k , compute βglassβglassbeta_glass, the coefficient of volume expansion of the glass.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Ibelieve the answer is d. titaniumhope my answer has you : )
