# Chemistry of making glass [closed]

To boil glass, the lime and sand mixture of potash was heated and the off gas spent $$\pu{125 mL}$$ of barley hydroxide solution (density $$\pu{1.14 g mL-1}$$). The mass of the sediment was $$\pu{4.925 g}$$. It is known that the ratio of gas to alkalinity is $$1 : 1$$.

1. Find the volume of absorbed gas.

2. Find mass of sodium hydroxide in solution.

This is a homework, I read the book a few times but didn't understand how to solve this. Can you please help me?

• "...didn't understand how to solve this" Surely you must've been taught something in this regard to go about solving this problem, otherwise your teacher wouldn't hand it to you. What exactly is it that you don't understand? – paracetamol Dec 14 '17 at 7:27
• The question is inconsistent! What is barley hydroxide? Is this supposed to mean barium hydroxide? In the context of the question and the compounds involved, this would make sense! If so, why is then asked for the remaining sodium hydroxide? – Klaus-Dieter Warzecha Dec 14 '17 at 7:57
