Given volume of hydrogen = 25 L
Standard temperature = 273 K
Standard pressure = 1 atm
R is gas constant = 0.08206 L.atm/(mol.K)
Plugging in the values in ideal gas equation and solving for moles of hydrogen (n):
n = 1.12 mol
Answer:
I think is the second one
Answer:
I pretty sure it's the pH level 7
