A2.37 l balloon contains .115 mol of xenon gas, xe(g), at a pressure of 954 torr. what is the temperature, in kelvin, of the xe in the balloon? express the answer using 3 significant figures.
Answer: because a mole is based on Avogrado's number, which is 6.02 x 10²³ particles. It isn't possible to directly count that many particles at a time.
Let the solution cool down really slowly, don’t disturb it at all.
Volume:
2.00 x 11.0 x 11.0 => 242 cm³
mass : 213 g
D = m / V
D = 213 / 242
D = 0.880 g/cm³
Answer B
hope this helps!
I believe the answer is C because the first two are mechanical hazards and C mentions plug which is electrical.
