Dipole-dipole interactions, and London dispersion interactions
Answer: 67 mmHg
Explanation:
According to Dalton's Gas Law, the total pressure of a mixture of gases is the sum of the pressure of each individual gas.
i.e Ptotal = P1 + P2 + P3 + .......
In this case,
Ptotal = 512 mmHg
P(oxygen) = 332 mmHg
P(carbon mono-oxide) = 113 mmHg
Remaining pressure (P3) = ?
To get P3, apply Dalton's Gas Law formula
Ptotal = P(oxygen) + P(carbon mono-oxide) + P3
512 mmHg = 332 mmHg + 113 mmHg + P3
512 mmHg = 445 mmHg + P3
P3 = 512 mmHg - 445 mmHg
P3 = 67 mmHg
Thus, the remaining pressure is 67 mmHg
A) C2H6O1
To find the emperical formula, divide each mole value by the smallest
For carbon, 0.013/0.0065 = 2
For hydrogen, 0.038/0.0065= 6
For oxygen, 0.0065/0.0065= 1
Emperical formula = C2H6O1
