Answer :
The atmospheric pressure of water if boiling at 81 °C will be 369 mmHg.
Explanation : The vapor pressure of boiling water can be calculated using the Antoine Equation:
log P = A - ,
where P is the pressure in mmHg,
A = 8.07131,
B = 1730.63
C = 233.426
and T = temperature in °C (81°C)
Substituting the given values, we get,
Log P = 8.07131−
Therefore, Log P =8.07131 − 5.5041 = 2.567.
Now, P = =369 mmHg.
Hence, the atmospheric pressure will be 369 mmHg.
Your answer would be, Sugar is the solute, and water is the solvent. a solution is the mixture of two, or more substances.
