Answer: $-272^0C$ .

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like $^0C$ and $K$

These units of temperature are inter convertible.

We are given:

Temperature of the gas = $655mK=0.655K$ (1mK=0.001 K)

Converting this unit of temperature into $^0C$ by using conversion factor:

$(t-273.15)^0C=tK$

$273.15K=0^0C$

Thus $0.655K=(0.655-273.15)^0C=-272^0C$

Thus the temperature is $-272^0C$ .

A sample of oxygen is collected over water at a total pressure of 692.2 mmHg at 17°C. The vapor pressure of water at 17°C is 14.

PtichkaEL [24]

Answer:

677.7 mmHg

Explanation:

This is Dalton's law, where you add each partial pressure into total.

You are given total pressure of 692.2 mmHg

Partical pressure of water is: 14.5 mmHg

To find the partial pressure of O2, you subtract the total pressure and the given vapor pressure of water.

If you want the answer in atm, it would be: 0.892 atm

677.7 mmHg X (1 atm/760 mmHg) = 0.892 atm

Hope this helps!
