Answer:
The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.
Explanation:
Assume that ethane behaves as an ideal gas under these conditions.
By the ideal gas law,
,
.
where
- is the pressure of the gas,
- is the volume of the gas,
- is the number of moles of particles in this gas,
- is the ideal gas constant, and
- is the absolute temperature of the gas (in degrees Kelvins.)
The numerical value of will be if , , and are in SI units. Convert these values to SI units:
- ;
- shall be in cubic meters, ;
- .
Apply the ideal gas law:
.
Answer:
19.8 kg of C₂H₂ is needed
Explanation:
We solve this by a rule of three:
If 1251 kJ of heat are relased in the combustion of 1 mol of acetylene
95.5×10⁴ kJ of heat may be released by the combustion of
(95.5×10⁴ kJ . 1) /1251kJ = 763.4 moles of C₂H₂
Let's convert the moles to mass → 763.4 mol . 26 g/1 mol = 19848 g
If we convert the mass from g to kg → 19848 g . 1kg / 1000g = 19.8 kg
