Answer: 672.2 grams
Explanation:
With 564.1 kJ of heat energy, 
moles of ethanol can be combusted.
So, we need to find the formula mass of ethanol.
- The atomic mass of carbon is 12 g/mol.
- The atomic mass of oxygen is 16 g/mol.
- The atomic mass of hydrogen is 1 g/mol.
- So, the formula mass of ethanol is
g/mol.
Therefore, the mass of ethanol is 
grams.
Answer:
"The number of air molecules above a surface determines air pressure. As the number of molecules increases, they exert more pressure on a surface, and the total atmospheric pressure increases. By contrast, if the number of molecules decreases, so too does the air pressure."
Answer: Yes because that's when they form a compound
