2 CH3OH + 3 02 2 CO2 + 4H2O What is the mass of oxygen (O2) that is required to produce 579 g of carbon dioxide (CO2)?
. Your answer should have three significant figures.

632 g

Explanation:

First we convert 579 g of CO₂ into moles, using its molar mass:

Then we convert CO₂ moles into O₂ moles, using the stoichiometric coefficients:

Finally we convert O₂ moles into grams, using its molar mass:

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
