The temperature of a gas is 30 degrees Celsius and its pressure is 760 torr. If the temperature originally
erastova [34]
T₁ = 40°C + 273.15 = 313.15 Kelvin T₂ = 30°C + 273.15 = 303.15 Kelvin

Solving Gay-Lussac's Law for P₁ we get:
P₁ = P₂ • T₁ ÷ T₂ P₁ = 760 torr • 313.15 K ÷ 303.15 K P₁ = 785.07 torr

Using the calculator, we click on the P1 button.
We then enter the 3 numbers 760 313.15 and 303.15 into the correct boxes then click "CALCULATE" and get our answer of 785.07 torr.

Using the potential given below, calculate the activity of cl^- in 1M KCl solution.
MissTica

Answer:

Explanation:

E° (calomel electrode) = 0.268 v

E( calomel electrode, 1M KCl) = 0.280 v

For calomel electrode

E = E^0 _( Hg^+/Hg ) - \frac{.059}{2} \times log( a_{cl^-} )^2

.280 = .268 - \frac{.059}{2} \times log( a_{cl^-} )^2

.012=  - \frac{.059}{2} \times log( a_{cl^-} )^2

log( a_{cl^-})^2= - .4067

a_{cl^-_}  = 0.626 .
