the pressure of 2.91 mil of gas in a rigid tank is 772 kPa what is the pressure if an additional 4.00 mol of gas is added to the tank

To find the new pressure after adding 4.00 mol of gas to the tank, we need to use the ideal gas law formula:
P1V1 = n1RT1
Where:
P1 = initial pressure = 772 kPa = 772000 Pa
V1 = volume of the tank (since it is rigid, volume is constant)
n1 = initial amount of gas = 2.91 mol
R = ideal gas constant = 8.31 J/(mol*K)
T1 = temperature (assume constant)
n2 = 4.00 mol (additional gas added)
Now we can rearrange the formula to solve for the new pressure (P2) after adding the additional gas:
P2 = (n1 + n2)RT1 / V1
P2 = (2.91 mol + 4.00 mol) * 8.31 J/(mol*K) * T / V1
P2 = 6.91 mol * 8.31 J/(mol*K) * T / V1
We do not have enough information to calculate the new pressure without knowing the temperature or volume of the tank.
