How many grams of bicarb soda are in one cup?

The amount of bicarb soda in one cup depends on the cup's size and the density of the bicarb soda. One US cup is equivalent to 240 ml, while one metric cup is equal to 250 ml. The density of bicarb soda (also known as baking soda or sodium bicarbonate) can vary slightly depending on factors like temperature and impurities, but it's generally around 2.16 grams per cubic centimeter (g/cm³). Here are the calculations for both US cups and metric cups:

US Cup (240 ml):

Volume = 240 ml = 240 cm³

Density of Bicarb Soda = 2.16 g/cm³

Mass of Bicarb Soda = Volume × Density

Mass = 240 cm³ × 2.16 g/cm³

Mass ≈ 518.4 grams (518 g)

Therefore, one US cup of bicarb soda is approximately 518 grams.

Metric Cup (250 ml):

Volume = 250 ml = 250 cm³

Density of Bicarb Soda = 2.16 g/cm³

Mass of Bicarb Soda = Volume × Density

Mass = 250 cm³ × 2.16 g/cm³

Mass ≈ 540 grams (540 g)

So, one metric cup of bicarb soda is approximately 540 grams.

It's important to note that these calculations provide an approximate value based on the standard volume and density of bicarb soda. In practice, the actual weight may vary slightly due to factors like packing and measuring conditions. For precise measurements, it's recommended to use a kitchen scale or measuring cup specifically designed for dry ingredients like baking soda.
