Answer: Spanish = La ley de Avogadro establece que "los volúmenes iguales de todos los gases, a la misma temperatura y presión, tienen el mismo número de moléculas". Para una masa dada de un gas ideal, el volumen y la cantidad (lunares) del gas son directamente proporcionales si la temperatura y la presión son constantes.
English = Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
The original compound is sodium hydrogen carbonate which have the chemical formula NaHCO₃.
Sodium hydrogen carbonate contains sodium (Na), hydrogen (H), carbon (C) and oxygen (O).
Explanation:
We have the following chemical reaction when sodium hydrogen carbonate (NaHCO₃) is heated to produce carbon dioxide (CO₂), water (H₂O) and sodium carbonate (Na₂CO₃):
2 NaHCO₃ → CO₂ + H₂O + Na₂CO₃

Hello there!
In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

<u>Answer:</u>
= 0.0908 M
<u>Explanation:</u>
Using the dilution formula;
M1V1 = M2V2
where M1 is the initial concentration, V1 is the initial volume, M2 is the concentration attained while V2 is the new volume.
Therefore;
M2 = M1V1/V2
M1 = 0.455 M
V1 = 375 mL or 0.375 L
V2 = 1.88 L
Thus;
M2 = (0.455 × 0.375)/1.88
<u>= 0.0908 M</u>
