Answer: The fraction of the bonding that is ionic is 0.08875.
Explanation:
Percentage ionic character is calculated using the formula:
% ionic character =![[16\times \Delta E_N + 3.5\times (\Delta E_N)^2]](https://tex.z-dn.net/?f=%5B16%5Ctimes%20%5CDelta%20E_N%20%2B%203.5%5Ctimes%20%28%5CDelta%20E_N%29%5E2%5D)
Where, 
= electronegativity difference
Given : The electronegativities for Ga and P are 1.6 and 2.1 respectively.
Thus = electronegativity of phosphorous - electronegativity of galium = 2.1 -1.6 = 0.5
Therefore,
%ionic character = ![[16\times 0.5 + 3.5\times (0.5)^2]=8.875](https://tex.z-dn.net/?f=%5B16%5Ctimes%200.5%20%2B%203.5%5Ctimes%20%280.5%29%5E2%5D%3D8.875)
Fraction of ionic bond =
The fraction of the bonding that is ionic is 0.08875.
This equation is balanced because there are 8 atoms of carbon (C), 26 atoms of oxygen (O), and 20 atoms of hydrogen (H) on each side of the equation.
<span>Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.

Density = mass ÷ volume
<span>Measure the mass of copper piece and measure dimensions. Divide mass by volume</span>
