you must use the perfect gas law, I think
PV = nRT ... n = PV/RT
V = 22.414 liters
T = 273.15 K
P = 101325 pascal
n = 1 mole
R = 8.31441 J K-1 mol-1
from that 1 CC STP (at 101325 pascal or 1.01325 bar ) is 1/22414 mole
= 4.4615E-5 (ie 44.615 µmoles <=> 1.01325 bar.cm3 <=> = 101325
pascal.mililiter)
so 1 bar.microliter is 44.615/1.01325/1000 = 0.044 µmole
so 10 bar.microliter is 0.44 µmole
best wishes
