If 0.750 L of argon at 1.50 atm and 177°C is mixed with 0.235 L of sulfur dioxide at 95.0 kPa and 63.0°C in a 1.00-L flask and the flask's temperature is adjusted to 25.0°C, what is the resulting pressure in the flask? 1 atm = 760 torr = 101.325 kPa; R = 0.0821 L.atm/mol.K

Please help me with this. I will immediately give you a thumb up. Thank you so much!  briefly describe the main idea of the variational principal and how it is used in the variational method?

Please show explanation

Help the other image shows the wrong answer. It's not either one together or individually

If given a value that is plot along x-axis: 1. Find given value along x axis. 2. From this point, trace a straight line vertically (parallel to the y-axis) until it intersects with the line graph. 3. Then, trace a line horizontally (parallel to the x axis) from the intersect to the y-axis. 4. The value of y corresponding to the given x value is where the traced line intercepts with the y- axis. Based upon what you see in the graph listed below, estimate the cost of the fence installation. 450 350 A 300 4 250 200 150 100 50 10 151 20 25 30 35 Cost (in $)

Am I wrong? Or is both answers correct?

Now how would you determine the endpoint from this graph?
