I weigh only water alone and it's 45.2g. I wonder whether the degree
of I tensity of Total Dissolved Solids has anything to do with weight
since espresso is 98% water.

Could you also weigh the remaining coffee, to check that mass is
maintained, just to be sure that you measures are accurate?

If everything is OK, you've just measured the extraction rate of your
process: 1.6/15.2*100 = 10.5%

thanks andy,
i just saw your chart in home-barista and am reading up the posts.
1.5oz is gross volume, so when i compare to your chart, it's large in
beverage grams, kinda low in gross volume. what about the TDS. would
it cause any weight different? what about measurement excluding crema?
yours,

Yes, without seeing your shot, that's what your numbers indicate.

I don't understand the questions, sorry.

You pulled a "longer" (more dilute) shot than most of us prefer. Your beans
were most likely very stale, because you had virtually no crema.
