Grease prevents water contact with the glass cylinder.
The difference between the weights (grams) of the empty cylinder, and with the liquid gives you the weight of the liquid. Divide that by 30 to get the density of the liquid in g/ml
To measure the amount of liquid in a specific manner
the most accurate would be a graduated cylinder but there are beakers and other things that aren't as accurate
First weigh a graduated cylinder. Then add the liquid. Then... Take away the figures and there you have it.
with a wrench or socket
No. There'll still be residual traces of R22, even if the cylinder is empty, and it won't blend with the R404A. Furthermore, the R22 cylinder will be labeled as such, and it's actually a crime to have such cylinders improperly labeled.

remove .5 mL of liquid
The Itasca Winnebago was produced from the 1960s to the 1990s. As of 2013, a 1988 Toyota 4-cylinder R22 foot Itasca Winnebago with 88,000 miles in good condition is worth around $7,000.
A graduated cylinder is used to find the VOLUME of a liquid.

30 pounds. Is the net weight of the product in a container in it`s liquid state. The vapor pressure within the container will vary according to the temperature of the container. But the net weight is 30 lbs, much like having a propane cylinder refilled.
You would obtain the mass of the liquid while it was in the measuring cylinder and then, from the combined mass, you would subtract the mass of the cylinder to obtain the mass of the liquid.
To measure the volume of a liquid, you can use a graduated cylinder.
