By counting squares in the following figure, estimate the fraction of argon atoms at T = 300 K that have speeds between 600 m/s and 800 m/s. The curve is correctly normalized. The value of a square is its length as measured on the x-axis times its height as measured on the y-axis, with the units given on those axes. `
