Which items are you asking about? This a chemical compound and it has 2 sodium, 2 hydrogen, 2 carbon, and 6 oxygen atoms.
The answer is NaHCO3
NaHCO3 = 84.007 g/mol Figure out the mole fraction = 2g / 84.007 g/mol The unit of the answer is mol, which in this context is the same as mole. Since you only have one carbon in NaHCO3 you cannot have more moles of CO2 than moles of NaHCO3.
Type your Nahco3+ H2O = na2co3 + CO2answer here...
The same amount.
Sodium carbonate is Na2CO3(the more familiar compound, baking soda, is sodium bicarbonate, NaHCO3)
Divide 6.10 (g NaHCO3) by 84.007 (g.mol−1 NaHCO3) to get 0.0726 mol NaHCO3
6 atams
2 NaHCO3 plus energy --> Na2CO3 plus CO2 plus H2O
Several part problem. Get molarity of NaHCO3. (150 ml)( M NaHCO3) = (150 ml)(0.44 M HCl) = 0.44 M NaHCO3 --------------------------- get moles NaHCO3 ( 150 ml = 0.150 Liters ) 0.44 M NaHCO3 = moles NaHCO3/0.150 Liters = 0.066 moles NaHCO3 ---------------------------------------get grams 0.066 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 5.54 grams NaHCO3 needed ---------------------------------------------answer
For this you need the atomic (molecular) mass of NaHCO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaHCO3=84.0 grams110 grams NaHCO3 / (84.0 grams) = 1.31 moles NaHCO3
5 M NaHCO3
The mass of oxygen is o,303 g.
The answer is NaHCO3
The ratio of NaHCO3 to WHAT!
what does nahco3 make up
3.00 grams NaHCO3 (1 mole/84.008 grams) = 0.0357 moles of sodium bicarbonate
NaHCO3 has 3 atoms (the subscript number of O) in 1 molecule, so .... in two molecules ....., you see
