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.

The density of ethanol, a colorless liquid that is commonly known as grain alcohol, is 0.798 g/mL Calculate the mass of 205 mL o
katovenus [111]

Answer:

Mass of 205 mL of the liquid is 164 g

Explanation:

We know, density=\frac{mass}{volume}

Here density of liquid is 0.798 g/mL and volume of liquid is 205 mL

So, mass of liquid = density\times volume

                              = (0.798 g/mL)\times (205 mL)

                              = 164 g

hence mass of 205 mL of the liquid is 164 g.
