## Homework Statement

I need to find the amount of H2 being lost to water by being stored underneath a column of water. About 16 mL of H2 is made and it displaces the column by 16 cm. However the total amount of water is 30 ml/30 cm. I'm not sure which relationship to use to find the pressure of the gas. I hypothesize that that pressure of the H2 is equal to the liquid pressure exerted by the water column on top of it.

## Homework Equations

p = ghd

C = P/k

k= 7.8 x 10^-4 mol/L*atm

3. The Attempt at a Solution

3. The Attempt at a Solution

p = ghd = (9.8m/s^2 x 0.30 m x 1000 kg/m^3)

= 2940 Pa

= 0.0290 atm

C = P/k = (0.0290 atm)/(7.8 x 10^-4 mol/l*atm) = 2.263 x 10^-5 mol/L

2.263 x 10^-5 mol/L x 0.016 L = 3.62 x 10^-7 moles H2 lost
