First step is to get the mass of water molecule in grams:
From the periodic table:
molar mass of hydrogen is 1
molar mass of oxygen is 16
molar mass of a water molecule = 2(1) + 16 = 18 gm
Now, to convert the gm into amu, all you have to do is multiply the gm you got by Avogadro's number as follows:
mass of water molecule = 18 x 6.22 x 10^23 = 1.1196 x 10^25 amu which is approximately 1 x 10^25 amu
<u>Answer:</u> The solubility of nitrogen gas at 5.00 atm is ![117.6mg/100g](https://tex.z-dn.net/?f=117.6mg%2F100g)
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
![C_{A}=K_H\times p_{A}](https://tex.z-dn.net/?f=C_%7BA%7D%3DK_H%5Ctimes%20p_%7BA%7D)
Or,
![\frac{C_{1}}{C_{2}}=\frac{p_{1}}{p_2}](https://tex.z-dn.net/?f=%5Cfrac%7BC_%7B1%7D%7D%7BC_%7B2%7D%7D%3D%5Cfrac%7Bp_%7B1%7D%7D%7Bp_2%7D)
where,
are the initial concentration and partial pressure of nitrogen gas
are the final concentration and partial pressure of nitrogen gas
We are given:
![C_1=56.0mg/100g\\p_1=2.38atm\\C_2=?\\p_2=5.00atm](https://tex.z-dn.net/?f=C_1%3D56.0mg%2F100g%5C%5Cp_1%3D2.38atm%5C%5CC_2%3D%3F%5C%5Cp_2%3D5.00atm)
Putting values in above equation, we get:
![\frac{56.0mg/100g}{C_2}=\frac{2.38atm}{5.00atm}\\\\C_2=\frac{56.0mg/100g\times 5.00atm}{2.38atm}=117.6mg/100g](https://tex.z-dn.net/?f=%5Cfrac%7B56.0mg%2F100g%7D%7BC_2%7D%3D%5Cfrac%7B2.38atm%7D%7B5.00atm%7D%5C%5C%5C%5CC_2%3D%5Cfrac%7B56.0mg%2F100g%5Ctimes%205.00atm%7D%7B2.38atm%7D%3D117.6mg%2F100g)
Hence, the solubility of nitrogen gas at 5.00 atm is ![117.6mg/100g](https://tex.z-dn.net/?f=117.6mg%2F100g)
The answer is: emitted gas is carbon dioxide (CO₂).
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda)
Balanced chemical reaction of vinegar and antacid:
CH₃COOH(aq) + NaHCO₃(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).
Sodium acetate (CH₃COONa) is a salt.
Sodium bicarbonate (NaHCO₃) is an antacid. Sodium bicarbonate is the active ingredient in baking soda.
The reaction between an organic acid and an alcohol produces an Ether.
