Determine the volume, in liters, occupied by 0.080 moles of a gas at STP.

V = 1.79 L

Explanation:

Given data:

Volume of gas = ?

Number of moles of gas = 0.080 mol

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

1 atm × V = 0.080 mol × 0.0821 atm.L/ mol.K  × 273.15 K

V = 1.79  atm.L / 1 atm

V = 1.79 L

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
