The correct answer is option B, that is, hypothesis.
A hypothesis refers to an anticipated illustration for an occurrence. It refers to a proposed illustration or a supposition made on the groundwork of inadequate proof as an initiation point for further investigation. In order for a hypothesis to be a scientific hypothesis, the scientific method needs that one can examine it.
Last one cuz it stay in the air for a while then swings making it kinetic
Answer:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
Explanation:
Hello,
In this case, since molarity is mathematically defined as the moles of solute divided by the volume of solution and the weight/weight percent as the mass of solute divided by the mass of solution, we need:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
For instance, if a 1-M solution of HCl has a density of 1.125 g/mL, we can compute the w/w% as follows:
![w/w\%=1\frac{molHCl}{L\ sln}*\frac{36.45gHCl}{1molHCl}*\frac{1L\ sln}{1000mL\ sln}*\frac{1mL\ sln}{1.125g\ sln} *100\%\\\\w/w\%=3.15\%](https://tex.z-dn.net/?f=w%2Fw%5C%25%3D1%5Cfrac%7BmolHCl%7D%7BL%5C%20sln%7D%2A%5Cfrac%7B36.45gHCl%7D%7B1molHCl%7D%2A%5Cfrac%7B1L%5C%20sln%7D%7B1000mL%5C%20sln%7D%2A%5Cfrac%7B1mL%5C%20sln%7D%7B1.125g%5C%20sln%7D%20%20%20%20%2A100%5C%25%5C%5C%5C%5Cw%2Fw%5C%25%3D3.15%5C%25)
Whereas the first factor corresponds to the molar mass of HCl, the second one the conversion from L to mL of solution and the third one the density to express in terms of grams of solution.
