# What is the mass of a sample of sodium bicarbonate in nanograms?

## Question:

What is the mass of a sample of sodium bicarbonate in nanograms?

## Answer:

The mass of the sample having 2.1 kg of sodium bicarbonate will be 2.1 x 10^12 ng.

**Explanation:** We are given a sample of sodium bicarbonate (NaHCO3) with a mass of 2.1 kg. To convert this into nanograms, we use the following conversions:

1 kg = 1000 grams

1 gram = 10^9 nanograms

Converting 2.1 kg to nanograms using the above conversions:

2.1 kg = 2.1 x (1000 x 10^9) ng = 2.1 x 10^12 ng

Therefore, the mass of the sample in nanograms is 2.1 x 10^12 ng. This shows that the sample of sodium bicarbonate is quite substantial when measured in nanograms.
