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.

Answer:
Explanation:
Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied being so far underground. Therefore, creating what we now know as Slate.
Volatility is a chemical property. The other ones are chemical properties
