My first reaction is what form of Henry's law are you using? What are the units of your Henry's Law constant?

Use Henry's law to determine the molar solubility of helium at a pressure of 1.5 atm and 25 degrees celsius .
this is what I know...
Sgas = kH x Pgas
so then I plugged in...
Sgas = 3.7 x 10-4 x 1.5
my answer was .055 and it is wrong.
could someone please help show me what I am doing wrong.

for sgas moles/liter and pgas m/atm
redo calculations...
(3.7*10^-4)*1.5=5.7*10^-4
(3.7*10^-4)*1.5=5.7*10^-4
