Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n = 
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n =
- for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
Ahh there isn’t a group 29 on the periodic table, but do you mean which element had the atomic number 29 because that would be Copper (Cu).
Hope this helps :)
Answer:
0.13 cm^3
Explanation:
Volume = Mass/ density
1.8 g/ml / 14g = 0.128571429
Both numbers have 2 significant digits.
With that, the answer rounds to 0.13
The final answer is 0.13 cm(don't forget the units for volume)
Hope it helped!
Rubisco is a super important enzyme in plants that first captures CO2 to begin the process of the Calvin cycle. It's the most important enzyme by far because it starts the entire process of Carbon Fixation.
