# Calculate the Mass of NaCO3 Used in Experiment

## What is the mass of sodium bicarbonate (NaHCO₃) used in the experiment?

Can you calculate the mass of NaHCO₃ used based on the given data?

## Answer:

The mass of sodium bicarbonate (NaHCO₃) used in the experiment is 1.997 g.

To calculate the mass of NaHCO₃ used in the experiment, we need to subtract the mass of the empty evaporating dish from the mass of the evaporating dish with sodium bicarbonate. The given data shows that:

Mass of empty evaporating dish: 46.233g

Mass of evaporating dish + sodium bicarbonate: 48.230g

To find the mass of sodium bicarbonate, we subtract the mass of the empty evaporating dish from the mass of the evaporating dish with sodium bicarbonate:

**Mass of sodium bicarbonate (NaHCO₃) = Mass of evaporating dish + Sodium bicarbonate - Mass of empty evaporating dish**

Mass of sodium bicarbonate (NaHCO₃) = 48.230g - 46.233g

Mass of sodium bicarbonate (NaHCO₃) = 1.997 g

Therefore, the mass of sodium bicarbonate (NaHCO₃) used in the experiment is 1.997 g.
