Answer to Question #291122 in General Chemistry for Johnrey

Question

Lean meat is marinated and added moisture through brining. In brining, a mixture of salt and water is used to soak the meat for a few hours or days before cooking.

Basic Brine: Make 3880 grams brine for 2.72 kg of meat

Procedure:

a. Mix 250 grams of salt (NaCl) with 3880 grams of water.

b. If you make sweet brine, mix 250 grams of sugar (C₁₂H₂₂O₁₁) to solution of salt and water.

Problem: What is the molal concentration of the brine solution (250 g salt + 3880 g water)?

Answer 1

Molar mass of NaCl= 58.44g

Moles in 3880 g of water=$\frac{250}{58.44}$

Concentration$=\frac{1000}{3880}×\frac{250}{58.44}$

$=1.1025M$
