how can add mass,weight, material to my part
You need to select a material first. Right click the Material entry in the Feature Tree and select Edit Material. From there you can select a material from Solidworks built-in material databases. Once you have selected the material, click on the Evaluate tab and select Mass Properties to get Mass and its center.
You can also add Material and Weight as a Custom Property for use in drawings.
I would do it to your file but I don't have the older version of SW installed.
