Answer:
The pressure inside the container is 34.97 atm
Explanation:
Given:
V=50L R= 0.0821LatmK^-1mol^-1
n= 45mol T= 473k
PV=nRT
P= nRT/V
= 45mol*0.0821Latmmol^-1K^-1*473K/ 50L
=34.95atm
Answer:
Object 2 with a density of 0.68
Explanation:
object 2 has a lower density than water so it will float
It can be oxygen in only 1 atom. All elements on the periodic table can stand alone in one atom.
(I took a lucky guess, using some of my knowledge about elements )
