Skew-T procedure to determine mixing ratio

To find the mixing ratio (w) for a given pressure on the plotted sounding, read the value, either directly or by interpolation, of the saturation mixing-ratio line that crosses the Td curve at that pressure.

In this example, a parcel of air at 850 hPa with a dewpoint of -6°C has a mixing ratio of 3 g/kg.
