10 points The full chemical equation for photosynthetic production of algae in seawater is: => 1 C106H2630130N16P+138 0₂ 106 CO₂+16HNO3+1H₂PO4+122 H₂O where the compound C106H2630130N16P (molec. mass 3870 g/mole) represents the average atomic composition of algae. (Paytan and McLaughlin, The Ocean Phosphorous Cycle, Chem. Rev, 107,563-576 (2007) 10.1021/cr0503613) On average, there is approximately 6.4 x 105 g of carbon (C) present in a square kilometer of ocean (Arteaga et al., Seasonal modulation of phytoplankton biomass in the Southern Ocean, Nature Communications, 11, Article number: 5364 (2020) 10.1038/s41467-020-19157-2). ☆ Q1 (5 pts). If all 6.4 x 105 g of carbon (C) is present as C106H2630130N16P. how many moles of C100H2630130N16P are contained in a square kilometer of ocean? Q2 (5 pts). How many moles of O₂ were produced in producing that C106H2630130N16P? Hint: This problem just looks complicated because C106H2630130N16P seems like a complicated molecule. So, yeah, the numbers are big so you'll have to use a calculator. But this problem is nearly identical in terms of complexity to the Pivot hydrate lab you (should have) completed. The steps you want to follow are: 0. Don't panic. This isn't that complicated. Really. It just "looks ugly. 1. Convert "mass of carbon" to "moles of carbon" 2. Remember how to convert moles of carbon to moles of C106H2630130N16P using stoichiometry and the chemical formula for algae 3. Use the stoichiometry from the reaction to figure out how many moles of oxygen, O₂, are produced
