A chemical plant uses electrical energy to decompose aqueous solutions of NaCl to give Cl2,H2, and NaOH: 2NaCl(aq)+2H2O(l)→2NaOH(aq)+H2(g)+C l2(g) a) If the plant produces 1.4×106 kg (1400 metric tons) of Cl2 daily, estimate the quantities of H2 produced.

b) If the plant produces 1.4×106 kg (1400 metric tons) of Cl2 daily, estimate the quantities of NaOH produced.

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%
