Question
![### Waterproofing Cloth Using Silicone Compounds
Cloth can be waterproofed by coating it with a silicone layer. This is done by exposing the cloth to \((CH_3)_2SiCl_2\) vapor. The silicon compound reacts with \(OH\) groups on the cloth to form a waterproofing film (density = \(1.0 \, \text{g/cm}^3\)) of \([(CH_3)_2SiO]_n\), where n is a large integer number.
The chemical reaction is given by:
\[ n \, (CH_3)_2SiCl_2 + 2n \, OH^- \rightarrow 2n \, Cl^- + n \, H_2O + [(CH_3)_2SiO]_n \]
The coating is added layer by layer, with each layer of \([(CH_3)_2SiO]_n\) being \(0.60 \, \text{nm}\) thick. Suppose you want to waterproof a piece of cloth that is \(4.00 \, \text{m}^2\) and you want \(250\) layers of the waterproofing compound on the cloth.
**Question:**
What mass of \((CH_3)_2SiCl_2\) do you need?
