# = weighed wet a day later (but kept cold to reduce water loss)

Here is a quick comparison of the weights of various objects with the borrowed scale and ours. The borrowed scale read within 1g, so I wouldn't change any of the above readings.

ROUND THREE:
John, Tom, and Steve S
We tared the scale prior to weighing the wet soil (net), weighed the dry soil + pan (total), then subtracted the pan wt to get the dry soil (net).
I mistakenly started weighing the soil in ounces, so we continued this in order to make a consistent table.
Ring diameter = 2 3/32" = 2.094" = 5.319 cm; volume = 66.66 cm^3; 1 oz = 28.35 gm
Qsoil = 1 - dry/wet; h2o volume fraction = (wet-dry)/(1 gm per cm^3)/sample-volume
