Answer:
The mass density will be doubled
Explanation:
- Density is given by dividing the mass of a substance by its volume.
- An increase in mass causes an increase in density and vice versa, while a decrease in volume causes an increase in density and volume.
- Therefore, when the volume is halved, then the density will be doubled if the mass is kept constant.
- This has no effect on the number of moles as the mass is constant.
Density of a substance is defined as the mass of the substance divided by the volume.
Density of the substance= 0.242 g cm⁻³
volume of the substance= 2.50 in³
As, 1 in³= 16.39 cm³
So, 2.50 in³= 16.39× 2.50 cm³=40.97 cm³
As ,
Mass=volume ×Density
Mass=40.97 × 0.242
Mass=9.916 g.

This doesn't seem like a question -_-
Answer is: group 17 on the periodic table.
Group 17 (halogens) elements are: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).
They are very reactive and easily form many compounds.
Fluorine and chlorine are in gaseous state, bromine is liquid and iodine is in solid state in room temperature.
Halogens need to gain one electron to have electron cofiguration like next to it noble gas.
For example, fluorine has 9 electrons and it gain easily one electron in chemical reaction to have electron configuration like noble gas neon (Ne) with 10 electrons.
