Answer:

Option A = atomic masses

Explanation:

In compound molecular mass is the sum of the individual atomic masses of the atoms.

For example

Compound NaCl.

atomic weight of sodium = 23 g/mol

atomic weight of chlorine = 35.5 g/mol

Molar mass of NaCl = 23+ 35.5 = 58.5 g/mol

Every atom consist of nucleus or a positive center. The protons and neutrons are present with in the nucleus while electrons are present out side the nucleus. All these three subatomic particles construct an atom. The number of protons or number of electrons are the atomic number of an atom while the number of protons and number of neutrons are the mass number of an atom. A neutral atom have equal number of protons and electrons. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.

Calculate the pH of a solution with an H+ ion concentration of 9.36 x 10-3 M ?
mel-nik [20]

Answer:

The answer is 2.03

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

where H+ is the Hydrogen ion concentration

From the question we have

pH =  -  log(9.36 \times  {10}^{ - 3} )  \\  = 2.02872415...

We have the final answer as

<h3>2.03 </h3>

Hope this helps you
