The weight of a cup of sodium bicarbonate, commonly known as baking soda, is approximately 220 grams or around 7.7 ounces. This weight can slightly vary depending on how densely the baking soda is packed into the cup. For instance, if it is spooned in and lightly leveled, it may weigh a bit less. Conversely, if it’s scooped directly from the container, compacting it may result in a heavier measurement.
It’s essential to note that baking soda is relatively light compared to many other dry ingredients. When measuring for recipes, using a kitchen scale can help ensure accuracy, especially for baking where precise measurements can significantly affect the outcome.
