Hello!
The pressure of the Ideal Gas when the volume is 1,45 L and the temperature is 298 K is
1,82 atm.
To solve this problem we need to apply the
Ideal Gas Law for the initial conditions and the final ones, clearing the equation for the number of moles (n) and the ideal gas constant (R) which remain constant:

Now we match n*R for the initial conditions (1) and the final ones (2), clearing the equation for P₂

Have a nice day!
The formula for specific gravity is:

where
is the density of the substance and
is the density of water.
The density of water,
= 
Substituting the values in above formula we get,


The formula of density is:

The density of mercury is 
The mass of mercury is 
Substituting the values in density formula:
