How many molecules, N, are in m=7.27×10−19 grams of carbon dioxide, CO2 ? (atomic masses: C= 12u;O=16u ). Please round your answer to the nearest whole number (integer). Equation: N=MmNA where M is the molar mass of CO2 ...
In glycolysis, how many molecules of carbon dioxide are produced per molecule of glucose? How many ATP molecules are made through glycolysis and how many through the Krebs cycle? How much ATP energy would you get from a tripeptide that, upon hydrolysis and deamination, makes ...
What is the mass, in grams, of a CO_2 sample that contains 3.91 \times 10^{24} \ CO_2 molecules? Use the periodic table to calculate the mass percent of carbon (C) in carbon dioxide (CO2). A. 27.3% B. 42% C. 37.5% D. 100% How many grams of glucose are produced from 15....
The carbon dioxide enters the plants through tiny holes or pores (气孔) on the surface of leaves.However, each time a plant takes in one molecule (分子) of carbon dioxide gas, it loses hundreds of water molecules.Scientists say plants lose ninety-five percent of the water they take in ...
How many molecules of CO2 are produced from 5.0 moles of C4H10? 2H2(g) + O2(g) 2H2O(g) + Heat. If 25.0 grams of H2(g) is mixed with 197 grams of O2(g), how many grams of H2O(g) is produced? (The molar mass of hydrogen is 1.01 g/mol and oxygen is 16.00 g...

For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's ...
