Answer to Question #162428 in Chemistry for carly

Question

how many miles of H2O will be produced from 2.9g of HCL reacting with Ca(OH)2

Answer 1

Solution:

The balanced chemical equation:

Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O

According to the equation above: n(HCl) = n(H₂O)

Moles of HCl = Mass of HCl / Molar mass of HCl

The molar mass of HCl is 36.458 g mol^-1.

Hence,

n(HCl) = 2.9 g / 36.458 g mol^-1 = 0.07954 mol

n(H₂O) = n(HCl) = 0.07954 mol

Moles of H₂O = 0.07954 mol = 0.080 mol

Answer: About 0.080 moles of H₂O will be produced.
