Hi, I don't have a scale and am trying to figure out how many ounces of (Leslie's) soda ash go in a regular measuring cup. I've been searching the web and TFP to no avail so far, so I've created an account to ask this question.
P.S. I was going to ask the same about (Arm and Hammer) baking soda, but I found at gourmetsleuth.com that 4.6 grams = 1 tsp, so assuming that's correct...
4.6 g/tsp * 48 tsp/C = 220.8 g/C
220.8 g/C / 28.35 g/oz =
7.79 oz/C for baking soda
Sanity check: 1.5 C removed a fraction around a sixth of a 5-lb bucket, which is about 8.93 oz/C. Kind of close.
