Answer:
A) 22.4L
Explanation:
we know, ideal gas law states
PV=nRT
V=nRT/P
At STP,
T= 273.15K P=1atm R=0.082L.atm/mol/K n=1 mole
V=(1*0.082*273.15)/ 1
V=22.4L
Answer:
is any thing which has mass volume and empty space
The answer is c. hg (mercury)
The energy at n level of hydrogen atom energy level =13.6/n^2

Answer:
A) wrong. The molar is same so A is hevier
B)
Explanation:
Xg/mol × (same molar)= g
→ bigger molar bigger mass
