Measuring Mimosa hostilis

I bought some mimosa recently and I don't have a way of measuring it out. I have a scale at my house but i'm at a friend's house on the opposite side of the country. Is there a way that I can measure out 20 grams of mimosa without a scale. It would be to get me by this one time.

well you must know what your total amount is right? you can either eyeball it or
just make the brew with all of it. volume of brew can be measured . ie 100g mimosa tea that is 5 cups total volume, so there is 20 g mimosa per cup.. or whatever..unused tea keeps very well in the fridge.
