Answer:
112.2L
Explanation:
Volume (V) = 300g
Temperature (T) = 822K
Pressure (P) = 0.9atm
using the ideal gas equation;
Molar gas constant (R) = 
Mole (n) = 
Molar mass of Mercury = 200.59g/mol
= 1.496mol
Now, the volume can be calculated;
V = 
∴Volume of mercury = 
Physical properties are properties that change form but not it's chemical compound
chemical properties are properties that change in chemical substance like burning tearing
The boiling points of alkanes increases with increasing number of carbons. This is because the intermolecular attractive forces, although individually weak, become cumulatively more significant as the number of atoms and electrons in the molecule increases.
So therefore your answer choice will increase. (B)
10 because you divide 200 by 20
