The principal ingredient of glass is quartz sand (SiO₂).
You have to use the equation F=ma and solve for m to get m=F/a.
m=mass in kg
F=force (in this case 350N)
a=acceleration (in this case 10m/s²)
when you plug everything in you should find that m=35kg
I hope this helps.
A model showing that gases are made from the matter of particles that are too small to see and are moving freely around in space can explain many observations.
