The mass of a sample of sodium bicarbonate is 2.1 kilograms (kg). there are 1,000 grams (g) in 1 kg, and 1 mc020-1.jpg 109 nanograms (ng) in 1 g. what is the mass of this sample in ng? 2.1 mc020-2.jpg 103 ng 2.1 mc020-3.jpg 106 ng 2.1 mc020-4.jpg 109 ng 2.1 mc020-5.jpg 1012 ng

The mass of the sample having 2.1 kg of will be

Explanation: We are given a sample of sodium bicarbonate having mass 2.1 kg

To convert this into nano-grams, we use the following conversions:

1 kg = 1000 grams

and

Converting 2.1 kg to nano-grams using above conversions:

the atomic mass is the bottom number on the element.
