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.
Explanation:
The given data is as follows.
= 4.60 L,
= 365 mm Hg
= 2.60 L,
= ?
= (20 + 273) K = 293 K,
= (36 + 273) K = 309 K
Since, number of moles of gas are equal so, according to ideal gas equation:
=
=
= 681.03 mm Hg
Thus, we can conclude that new pressure is 681.03 mm Hg.
