Answer:

See explanation

Explanation:

Number of protons = 28

Number of neutrons = 28

Mass of each proton = 1.007277 amu

Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu

Mass of each neutron = 1.008665 amu

Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu

mass defect of nickel-56  = 0.4667 amu

Binding energy = Δmc^2

Binding energy = 0.4667 *(3 * 10^8)^2

Binding energy =4.2 * 10^16 J

Binding energy per nucleon = 4.2 * 10^16 J/56

Binding energy per nucleon = 7.5 * 10^14 J

A bottle of wine contains 9.81 grams of C2H5OH, dissolved in 87.5 grams of water. The final volume of the solution is 100.0 mL.

Answer:

[EtOH] = 2.2M and Wt% EtOH = 10.1% (w/w)

Explanation:

1. Molarity = moles solute / Volume solution in Liters

=> moles solute = mass solute / formula weight of solute = 9.8g/46g·mol⁻¹ = 0.213mol EtOH

=> volume of solution (assuming density of final solution is 1.0g/ml) ...

volume solution =  9.81gEtOH + 87.5gH₂O = 97.31g solution x 1g/ml = 97.31ml = 0.09731 Liter solution

Concentration (Molarity) = moles/Liters = 0.213mol/0.09731L = 2.2M in EtOH

2. Weight Percent EtOH in solution (assuming density of final solution is 1.0g/ml)

From part 1 => [EtOH] = 2.2M in EtOH = 2.2moles EtOH/1.0L soln

= {(2.2mol)(46g/mol)]/1000g soln] x 100% = 10.1% (w/w) in EtOH.
