Asample of nitrogen gas, n2, is collected in a100 ml container at a pressure of 688 mm hg and a temperature of 565 °c. how many grams of nitrogen gas are present in this sample?

The mass of nitrogen gas present in the given sample is 0.037 g

Explanation:

To calculate the number of moles, we use the equation given by ideal gas equation:

Or,

where,

P = Pressure of the gas = 688 mmHg

V = Volume of gas = 100 mL = 0.1 L    (Conversion factor:  1 L = 1000 mL)

m = Mass of nitrogen gas = ?

M = Molar mass of nitrogen gas = 28 g/mol

R = Gas constant =

T = Temperature of the gas =

Putting values in above equation, we get:

Hence, the mass of nitrogen gas present in the given sample is 0.037 g

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

the temperature of the gas, in k, not celsius.
