2. A L flask contains argon at 3.50 atm and 127^circ C How many moles of argon are present?

To find the number of moles of argon present in the flask, we can use the ideal gas law equation:PV = nRTWhere:P = Pressure (in atm)V = Volume (in L)n = Number of molesR = Ideal gas constant (0.0821 L·atm/mol·K)T = Temperature (in Kelvin)Given information:- Pressure (P) = 3.50 atm- Temperature (T) = 127°C = 400.15 K (converted to Kelvin)We need to find the number of moles (n).Rearranging the ideal gas law equation to solve for n:n = (PV) / (RT)Substituting the given values:n = (3.50 atm × 2.00 L) / (0.0821 L·atm/mol·K × 400.15 K)n = 106.6 molesTherefore, there are 106.6 moles of argon present in the 2.00 L flask at 3.50 atm and 127°C.
