Homework Statement
NaOH(aq) + HCl(aq) ------> NaCl(aq) + H2O(l)
50mL of 1.0M HCl and 50ml 1.0M NaOH was mixed. Total heat is 2826J. If the density of 0.5M NaCl produced in this reaction is 1.02g/mL:
a) What is the mass of the solution?
b) Moles of water formed
c) Moles of NaCl formed
d) Molar heat of reaction
Homework Equations
The Attempt at a Solution
a) 1.02g/ml x 100ml = 102 g
b) 50ml x 0.001 x 1M =0.05 moles of Water
d) 2826/0.05 = 56.52kJ
Iam very confused about c). Why is there "0.5M"in the question? Do I have to use that molarity during calculation?
