NaHCO3 is chemically named as sodium hydrogen carbonate. However, scientifically, and commerically it is also known as sodium bi-carbonate It other name is 'baking powder'. as it is used in bakery to make dough rise.

The mass of oxygen is o,303 g.
Remember moles = mass(g) / Mr The 'Mr' is the relative molecular mass. The Mr(Baking soda ; sodium hydrogen carbonate ; NaHCO3) is Na x 1 = 23 x 1 = 23 H x 1 = 1 x 1 = 1 C x 1 = 12 x 1 = 12 O x 3 = 16 x 3 = 48 23 + 1 + 12 + 48 = 84 ( Mr of NaHCO3) Hence mol(NaHCO3) = 2.00g / THe answers!!!!!
This is the percent chemical composition.
The percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate (NaHCO3) is 27,38 %.

The chemical equation for baking soda is NaHCO3 - Sodium BicarbonateThe proper chemical name for sodium bicarbonate or baking soda is sodium hydrogen carbonate. The chemical formula for sodium bicarbonate is NaHCO3. The molecular mass or molar mass of sodium bicarbonate is 84.007 g/mol

All you need is the moles and the mass of NaHCO3 and you have the moles 0.025 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 2.1 grams of sodium bicarbonate ---------------------------------------------
The molar mass of sodium chloride is 58,44 g. The molar mass of sodium bicarbonate is 84,007 g. The ratio is 1,437.
Pure baking soda is actually sodium bicarbonate, or sodium hydrogen carbonate. It has chemical formula NaHCO3.Formula mass of NaHCO3 = 23.0 + 1.0 + 12.0 + 3(16.0) = 84.0So, amount of NaHCO3 = 16/84.0 = 0.190molIn each formula unit of NaHCO3 there are three oxygen atoms.Number of moles of O = 3 x 0.190 = 0.571molThere are 0.571 moles of O atoms in 16g NaHCO3.The Avogadro's number is 6.02 x 10^23Therefore, number of oxygen atoms = 0.571 x 6.02 x 10^23 = 3.44 x 10^23
Sodium chloride contain 39,665 83 % sodium.
To calculate you first have to find the molecular mass of NaHCO3. This is the formula for baking soda (also known as sodium bicarbonate).Atom Atomic weightNa = 22.98976928H = 1.00794C = 12.01073*O = 47.9982 (15.9994*3) +Total= 84.00660928So if you round that off, it's 84.0066.This number has another interesting property, the atomic weight is the same as the molecular weight (in grams) if you take a mole of molecules.So 1 mole of baking soda weighs 84.0066 grams, or to write it shorter 84.0066 grams/mole.0.025 moles is a simple calculation away:0.0025 moles *84.066 g/mole= 0.21 grams
The percentage of sodium in sodium chloride is 39,665 83 %. Mass of NaCl = Mass of sodium X 2,51
