Answer:
168.72 grams
Explanation:
Density = Mass/Volume
Volume = 14.8
Mass = ?
Density = 11.4
Let x = mass
11.4 = x/14.8
Multiply both sides by 14.8
14.8(11.4 = x/14.8)
x = 168.72
Mixture. Mixtures can be separated into their component parts, while substances are chemically bonded atoms that can't be separated by physical means.
The subatomic particle that plays the greatest role in determining the physical and chemical properties of an element is the electron.

The answer is there is a one-to-one ratio of potassium ions to iodide ions.
Explanation :
- (K) belongs to Alkali metals in group (1A) that contains (1) electron in the outermost energy level, whereas, (I) is from halogens in group (7A) that contains (7) electron in the outermost energy level.
- To achieve stability, both atoms tend to reach the nearest noble state (outermost level occupies 8 electrons). Therefore, (K) loses its outer electron and gives it to (I) which now has a completely filled outer level and an ionic bond is formed between the two.
- The valency (number of electrons lost, gained or shared) of both atoms is equal ”monovalent” which means one-to-one ratio..
