I think it's 2 I tried looking it up because I was not sure.
Answer:
The answer to your question is 1.11 M
Explanation:
Data
volume 1 = 287 ml
concentration 1 = 1.6 M
volume 2= 412 ml
concentration 2 = ?
Formula
Volume 1 x concentration 1 = Volume 2 x concentration 2
Solve for concentration 2
concentration 2 = (volume 1 x concentration 1) / volume 2
Substitution
concentration 2 = (287 x 1.6) / 412
Simplification
concentration 2 = 459.2 / 412
Result
concentration 2 = 1.11 M
I believe it’s Refractive index
The property of mixture which describes a mixture are it can be separated by physical methods, it can appear different from different sources and it cannot be described by a chemical symbol or formula.
<h3>What are mixtures?</h3>
Mixtures are the compounds which are formed by the addition or combination of one or two elements or compounds.
As in the mixtures many states of matters are present and it will be filtered by using various physical methods, and it is not chemically shown by single chemical symbol or formula. Mixtures are also of two types:
- Homogeneous mixtures are those in which equal compositions all over the volume is present.
- Heterogeneous mixtures are those in which different composition all over the volume is present.
Hence options (1), (3) and (4) are correct.
