Asample of gas with a mass of 8.40 g occupies a volume of 4.50 l at 298 k and 1.10 atm. what is the molar mass of the gas?

41.5225 g/mol

Explanation:

Given that:

Pressure = 1.10 atm

Temperature = 298 K

Volume = 4.50 L

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

1.10 atm × 4.50 L = n × 0.0821 L.atm/K.mol × 298 K  

⇒n = 0.2023 moles

Given that : Amount = 8.40 g

Molar mass = ?

The formula for the calculation of moles is shown below:

Thus,

answer; protein;

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
