What is the solubility of helium (in units of grams per liter) in water at 25 c, when the he gas over the solution has a partial pressure of 0.284 atm? ky for he at 25 °c is 3.26x10 moll atm

9.2584 mol/L is the solubility of helium in water at 25 °C.

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,

= Henry's constant =

= partial pressure of carbonated drink = 0.284 atm

Putting values in above equation, we get :

9.2584 mol/L is the solubility of helium in water at 25 °C.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
