If 1.00 mol of co2 gas at 350 k is confined to a volume of 400 cm3, find the pressure pideal of the gas using the ideal gas equation.

               71.8 atm

Solution:

Data Given:

                     Number of Moles  =  n  =  1.0 mol

                     Temperature  =  T  =  350 K

                     Volume  =  V  =  400 cm³  =  0.4 L

                     Gas Constant  =  R  =  0.082057 atm.L.mol⁻¹.K⁻¹

Formula Used:

Ideal Gas Equation is given as,

                     P V  =  n R T

Solving for Pressure (P),

                     P  =  (n R T) ÷ V

Putting values,

                     P  =  (1.0 mol × 0.082057 atm.L.mol⁻¹.K⁻¹ × 350 K) ÷ 0.4 L

                     P  =  71.8 atm

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.

the answer is b. dilution
