1eV --------- is ----------- 1.6*10⁻¹⁹J
1.931eV ---- is ----------- x
x = [1.931eV*1.6*10⁻¹⁹J]/1eV ≈ 3,1*10⁻¹⁹J
<u>ANSWER E</u>
Answer: The amount of coffee is the same
Explanation: This was the correct answer for me.
The mole is 0.749 because molar mass of AgNO3=170g/mol and mole=mass/molar mass.
mole=127.4g/170g/mol
Pt = p1 + p2 + p3, p1 = pp (CO) atm
2.68 atm = p1 + 1.56 atm + 0.65 atm
2.68 = p1 + 2.21
p1 = 2.68 - 2.21
p1 = 0.47 atm
