<u>Answer:</u> The volume of the container is 
<u>Explanation:</u>
To calculate the volume of water, we use the equation given by ideal gas, which is:

or,

where,
P = pressure of container = 200 kPa
V = volume of container = ? L
m = Given mass of water = 2.61 kg = 2610 g (Conversion factor: 1kg = 1000 g)
M = Molar mass of water = 18 g/mol
R = Gas constant = 
T = temperature of container = ![200^oC=[200+273]K=473K](https://tex.z-dn.net/?f=200%5EoC%3D%5B200%2B273%5DK%3D473K)
Putting values in above equation, we get:

Converting this into cubic meter, we use the conversion factor:

So, 

Hence, the volume of the container is 
Answer : The total pressure in the flask is 1.86 atm.
Explanation :
First we have to calculate the pressure of
gas.
Using ideal gas equation :

where,
P = Pressure of
gas = ?
V = Volume of
gas = 765 mL = 0.765 L (1 L = 1000 mL)
n = number of moles
w = mass of
gas = 1.25 g
M = molar mass of
gas = 44 g/mol
R = Gas constant = 
T = Temperature of
gas = 
Putting values in above equation, we get:


Now we have to calculate the total pressure in the flask.

Given :


conversion used : (1 atm = 760 mmHg)
Now put all the given values in the above expression, we get:

Therefore, the total pressure in the flask is 1.86 atm.
