Ellen performed the experiment on the density of a gas using two half tablets of Alka-Seltzer, she found a density of
1.8x10 g/cm? Ned performed the same experiment using four half tablets of Alka-Seltzer and a larger collecting bottle. If
neither student made any errors, what should Ned find for the density of the gas, in g/cm3?
