Mass of weighing boat/glass beads?

When I was doing my lab I forgot to tear the mass of the weigh boat and my professor said that my mass of 40 glass beads was too much. If anyone has information on how much a weigh boat might weigh or how much 40 glass beads might weigh? Any help would be great! Plz don’t tell me to go weigh a weigh boat because this has to be due by tuesday and I want to finish the lab over the weekends.
This lab is for the standard deviation and my s.d. is too high so I cannot finish my lab until I find either the mass of 40 glass beads or the mass of the weigh boat.
