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
Answer: X2Y5
Explanation:
X has 2 dots and Y has 5 dots
Answer:
The answer is
<h2>8.33 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 60 mL
error = 65 - 60 = 5 mL
The percentage error is
We have the final answer as
<h3>8.33 %</h3>
