Explanation:

Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species. Marine biodiversity is usually highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future.

Explanation:

First we convert 34 g of O₂ into moles, using its molar mass:

Then we convert O₂ moles into Cs₂O moles, using the stoichiometric coefficients of the balanced reaction:

Now we convert 2.125 moles of Cs₂O into grams, using its molar mass:

598.85 g is the theoretical yield. Finally we proceed to calculate the percent yield:
