In a constant‑pressure calorimeter, 70.0 mL of 0.320 M Ba(OH)2
was added to 70.0 mL
of 0.640 M HCl.

The reaction caused the temperature of the solution to rise from 23.56 ∘C
to 27.92 ∘C.
If the solution has the same density and specific heat as water ( 1.00 g/mL
and 4.184J/g⋅°C,)
respectively), what is Δ
for this reaction (per mole H2O
produced)? Assume that the total volume is the sum of the individual volumes.

i dunno to many word

Explanation:

it should be all of them because it asks if you included all of those in your answer

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
