265.2 mmHg is the partial pressure of oxygen in 780 mmHg of total pressure.

Explanation:

The partial pressure of a gas is defined as the individual pressure of the gas in total mixture. In an ideal gas all the constituent gases have partial pressure some of which will give total pressure of the gas.

The partial pressure of a gas is calculated by

total pressure x mole fraction of the gas.

Mole fraction of the oxygen present is 0.34 as it is 34% of the total gas.

\frac{34}{100} = 0.34  is the mole fraction

Total pressure is given as 780 mm Hg

The partial pressure can be calculated using the above formula:

Putting the values in equation:

780 x 0.34

= 265.2 mm Hg is the partial pressure of oxygen.

In the measurement 0.503 L , which digit is the estimated digit ?
AysviL [449]
The estimated digit is dependent on the least count of the instrument being used. If the least count is 0.1 and the reading is between two divisions of the least count, then the estimated digit will be in the tenths, or 0.1 place. In this case, the estimated digit is 3, meaning the least count is 0.001.

Which has higher frequency - neutron or electron? Why?
Alexeev081 [22]
The electron has a higher frequency compared to the neutron. It can be explained by the way an electron orbits the nucleus of an atom. 

According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.  

<span>However, there are frequencies associated with each orbital.
