What is the mass defect of oxygen-16? assume the following: the atomic number of oxygen-16 is 8. the atomic mass of oxygen-16 is 15.9994 atomic mass units. the mass of one proton is 1.0073 atomic mass units. the mass of one neutron is 1.0087 atomic mass units.

To solve for the mass defect of the given atom, add up the individual masses of the nucleons, protons and neutrons. In this case, the total mass of the nucleons is solved through 8x(1.0073 + 1.0087) and is equal to 16.128. Subtracting the mass of the intact nucleus which is 15.9994 gives 0.1286. Thus, the mass defect is 0.1286. 

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
