Answer: 708.2 grams
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Given : 38 g of
is dissolved in 100 g of solution.
Density of solution = 1.285 g/ml
Volume of solution = 
Thus if 77.8 ml of
contains = 38 g of 
1.45L= 1450 ml of
contains =
of 
Therefore, the mass of the sulfuric acid in a car battery is 708.2 g
Nanochemicals can be defined as chemicals generated by using nanomaterials (materials that possess of size on nanometer dimensions). The nanochemicals are used in multiple different applications including chemical warfare, bicycle making, armor design and military weapons crafting. The most commonly used and observed nanochemicals are carbon nanotubes that are used a ton in industry for applications such as stronger materials (stronger bicycles).
Smart materials are exquisitely designed materials whose property(ies) can be modified with the use of an external stimulus such as temperature, stress, pH, and so on. Some examples of smart materials include shape memory materials, piezoelectric materials, ferrofluids, self-healing materials, and such. Applications involve memory pillows, memory based solar panels (for satellites), light sensitive glasses, and so on.
Specialized materials are made specifically to perform a specified task or function. Applications involve electronic equipment (high purity silicon & germanium), machine tools (high tungsten high carbon steel), dental filling (dental amalgam), and so on.

It can be either they can have a negative or positive charge more specifically negatively charged molecule would called an anion and a positive one would be cation.
