I have used 0.1 g of photocatalyst in 20 ml aqueous solution and after irradiation with UV light, I am getting 5 ppm H2 gas.
Please let me know how to convert 5 ppm into micromolar per gram or any relevant units.

Hello,
the molary concentration = ppm /(( M.wt)*1000)
mol/L = (mg/mL)/ ( (g/mol)*1000)
micromol = (mol /1000000)
if you needed the other transfer
5 ppm in 20 mL
x in 1L
