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.
