Mass of water produced is equal to 7.2 grams.
The reactants are reacting according to the following equation:
HBr + NaOH = NaBr + H2O
1 mole of HBr requires 1 mole of NaOH to be totally transformed into NaBr and water.
Now, let us calculate the amounts of HBr and NaOH in mols:
m(HBr) = 67.2g
m(NaOH) = 16g
M(HBr) = 80.9g/mol
M(NaOH) = 40g/mol
Following the simple relation
n(moles) = m(grams)/M(g/mol)
n(HBr) = 67.2g/(80.9g/mol)
n(NaOH) = 16g/(40g/mol)
n(H2O) = n(NaOH) = 0.40 mol, which is:
m(H2O) = n(H2O) x M(H2O)
0.40mol∗18g/mol=7.2g
Finally, the mass of water produced is equal to 7.2 grams.

Missing question: <span> The vapor pressure of water at 26.4 °C is 25.81 mm Hg.
p(total) = p(H</span>₂O) + p(O₂).
p(total) = 817 torr; <span> total pressure of the mixture.
</span>p(H₂O) = 25.81 torr, <span>partial pressure of water.
</span>p(O₂) = 817 torr - 25.81.
p(O₂) = 791.19 torr; partial pressure of oxygen.
Pressure is defined as the force divided by the area perpendicular to the force over which the force is applied, or. A given force can have a significantly different effect depending on the area over which the force is exerted.
The K+ channel uses the energy in ATP hydrolysis to remove the hydration shell from the K+ion
All of this truly implies is that one of these bonds breaks in a hydrolysis process (a water-mediated breakdown reaction), releasing a sizable amount of energy.
The following reaction results in the hydrolysis of ATP to ADP:
ATP+H2O⇋ADP+Pi+energy
The hydrolysis of ATP to ADP is reversible, like the majority of chemical processes.
Energy is needed for the reverse process, which creates ATP from ADP and Pitext P iPi start subscript, P, end subscript, start subscript, I end subscript.
Because cells frequently use (hydrolyze) ATP molecules and depend on constant production of replacement ATP, ATP regeneration is crucial1^1.
Hence the K+ channel uses the energy in ATP hydrolysis to remove the hydration shell from the K+ion
