Respuesta :
The mass of the sample having 2.1 kg of sodium bicarbonate will be 2.1*[tex]10^{12}[/tex] ng.
Given,
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
1g = [tex]10^{9}[/tex]ng
Converting 2.1 kg to nano-grams using above conversions:
2.1 kg= 2.1*1000* [tex]10^{9}[/tex]=2.1*[tex]10^{12}[/tex]ng
Sodium bicarbonate
Sodium bicarbonate, also referred to as baking soda or bicarbonate of soda and with the IUPAC name sodium hydrogencarbonate, is a chemical substance having the formula NaHCO3. It is a salt made up of the cation sodium (Na+) and the anion bicarbonate (HCO3). Although it is a crystalline white solid, sodium bicarbonate frequently takes the form of a fine powder. It has an alkaline, slightly salty flavor similar to that of washing soda. Nahcolite is a type of natural mineral. It can be found dispersed in a lot of mineral springs and is a part of the mineral natron.
Because it has been around for a while and is often used, salt goes by several names, including baking soda, bread soda, cooking soda, and bicarbonate of soda. It is frequently seen next to baking powder in supermarkets.
