For equal moles of gas, temperature can be calculated from ideal gas equation as follows:
P×V=n×R×T ...... (1)
Initial volume, temperature and pressure of gas is 3.25 L, 297.5 K and 2.4 atm respectively.
2.4 atm ×3.25 L=n×R×297.5 K
Rearranging,
n\times R=0.0262 atm L/K
Similarly at final pressure and volume from equation (1),
1.5 atm ×4.25 L=n×R×T
Putting the value of n×R in above equation,
1.5 atm ×4.25 L=0.0262 (atm L/K)×T
Thus, T=243.32 K
Answer:
The choice that we had decided on doing today factors our future because whatever choice we decide on doing in the present day can impact how our life will play out in the future. ... After all, it is your life, so whatever you chose to do, you have the power to decide and create what you think would be best for you
Explanation:
I Would Think that the answer is 55.845 u ± 0.002 u
Or you could just do<u> 55.85 Grams</u>
I believe it would be the last one because you can use the molar mass of HCl to find the number of moles, then use Avogadro’s number to find the number of atoms
Hope this helps!
