Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places

In science why is it important to have more than one piece of evidence to support your claim?

My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

Current estimates suggest the number of prokaryotic organisms associated with the human body is equal to or greater than the num

Reika [66]

Answer:

Symbiotic relationship

Explanation:

An average human body between 20 to 30 year of age with a weight of 74 kg and 170 cm contains about 30 trillion cells. The number of bacterial cells in the same man counts for about 39 trillion that is higher than the cell of the body.

The ratio between the bacterial cell to the human cell is about 1.3:1 which is almost equal or higher than the human cells.

Although the number of bacteria is almost equal or higher than the human cell, the main reason behind this relation is that these bacteria live in the symbiotic or mutually beneficial relationship with humans.

Thus, a Symbiotic relationship is the correct answer.
