Mass number = protons + neutrons

If you have the # of protons and the mass #, subtract the number of protons from the mass number to get the number of neutrons.

If you have the number of neutrons and the mass number, subtract the number of neutrons from the mass number to get the number of protons.

<h3>Mass number:</h3>

The element's mass number is nothing but the sum of total number of neutrons and protons present in the element's nucleus. For example, if the mass number of nitrogen is 14, it means that there are 7 number of protons and 7 number of neutrons in the nucleus of the nitrogen.

The relationship between the number of proton and the neutron with that of mass number is that, the latter gives the count of the former. On contrary, the atomic number denotes the weight of the atom.

Aleks [24]

Answer:

Edema occurs when blood pressure exceeds the counteracting force of the vascullar walls in the bloodstream, so fluid remains in the spaces surrounding cells and body tissue swells.

Explanation:

The intravascular hydrostatic pressure increases due to an increase in fluids, therefore the vessel walls begin to perceive this increase in pressure in their walls, generating fluid extravasion to areas of lower pressure.

PolarNik [594]

All carbohydrates are made up of carbon, oxygen, and hydrogen.

The chemical formula for Glucose is $C_{6} H_{12} O_{6}$ .
The chemical formula for Fructose is the same as that of Glucose. The difference between the two is how they are structured.
The chemical formula for Sucrose is $C_{12} H_{22} O_{11}$ .

As you can see in the chemical formulas of Glucose, Fructose, and Sucrose, they are all made up of the elements carbon, hydrogen, and oxygen.
