It depends on the density of the particular brand of baking powder you are using. The best way to determine the weight in grams is using division: look at the baking powder container's label to determine how many grams is contained in the entire package, and divide that number by the number of tablespoons in the container. The result will be the number of grams of baking powder per tablespoon.
First, you measure the liquid with the container. After that, measure ONLY the container and then subtract the container itself from the container with the liquid. FOR EXAMPLE: If my apple juice w/ the container weighed 70 grams, and the container weighed 10 grams, the apple juice weighed 60 grams. :)
