Answer: Atoms (ions) are held together in an ionic bond through Electrostatic attraction

Explanation: Ions are atoms that lose or gain one or more electrons to become either positively or negatively charged, which are called anions and cations respectively. The cations are usually metals while anions are usually non-metals.

The bond (ionic bond) is formed when there is a transfer of valence electron(s) between the anion and the cation in order to obtain a full valence shell for both atoms.

Example of an ionic compound is NaCl.

Where: Na is the cation that looses a valence electron to become stable to Chlorine which is the anion that gained an electron to become stable.

At standard ambient temperature and pressure (SATP), a gas has density of 1.5328g/L. What is the molar mass of the gas?

ahrayia [7]

The standard ambient temperature and pressure are

Temperature =298 K

Pressure = 1atm

The density of gas is 1.5328 g/L

density = mass of gas per unit volume

the ideal gas equation is

PV = nRT

P = pressure = 1 atm

V = volume

n = moles

R= gas constant = 0.0821 Latm/mol K

T = 298 K

moles = mass / molar mass

so we can write

n/V = density / molar mass

Putting values

$Pressure=\frac{nRT}{V}=\frac{massXRT}{VXmolarmass}$

$Pressure=\frac{densityXRT}{molarmass}$

$molarmass=\frac{densityXRT}{Pressure}=\frac{1.5328X0.0821X298}{1}=37.50$

Thus molar mass of gas is 37.50g/mol

Okay so i think to calculate volume change you use the ideal gas law . this is pressure x volume = amount of substance x ideal gas constant x temperature. i honestly don’t know where to go from there but i hope this helped a bit :(
