When the number of moles = mass/molar mass
so the number of moles of CO = mass of CO sample/molar mass of CO
when the mass of CO sample = 36.55 g
and the molar mass of CO = 12 + 16 = 28 g/mol
by substitution:
∴moles of carbon monoxide = 36.55 g / 28 g/mol
= 1.3 moles
Answer:
this reminds me of biology
Explanation:
please dont delete this i'm gonna answer it later
You can either use an ice table or the Henderson-Hasselbalch equation. I would use the Henderson-Hasselbalch equation since that is the easiest method to use in my opinion. The Henderson-Hasselbalch equation is pH=pKa+log([A⁻]/[HA]).
pKa=-log(Ka) (which equals 1.77 in this question)
[A⁻]=concentration of conjugate base (0.386M in this question)
[HA]=concentration of acid (0.451M in this question)
When you plug everything in you should get a pH of 1.697.
I hope this helps. Let me know if anything is unclear or you want me to explain anything in more detail.
