Hello guys!

I hope you all are doing well!

I am trying to calculate the %wt. of hydrogen using the following equations provided in the research paper uploaded below, I am assuming 50 grams of LaNi5 for this calculations , I know that usually for the LaNi_5 as a hydride, the %wt. of hydrogen is about 1.5% , but I am getting higher values any suggestions and formula or corrections recommended.

The formula I am using is :

%wt. = mass of hydrogen(grams)/mass of LaNi5(grams) * 100

the paper I am using for calculating the desorption mass flow rate for hydrogen is uploaded below in g/cm^3-s. This paper is used as a reference for the calculations.

Thank you

regards
