What is the molar mass of an element?
Vesnalui [34]

The answer is: the mass of 6.02 x 1023 representative particles of the element.

The base SI unit for molar mass is kg/mol, but chemist more use g/mol (gram per mole).

For example, molar mas of ammonia is 17.031 g/mol.

M(NH₃) = Ar(N) + 3 · Ar(H) · g/mol.

M(NH₃) = 14.007 + 3 · 1.008 · g/mol.

M(NH₃) = 17.031 g/mol.

The molar mass (M) is the mass of a given substance (in this example ammonia) divided by the amount of substance.

Which of these refers to the concentration of an acid?
andrezito [222]

The concentration of an acid IS A MEASURE OF THE QUANTITY OF ACID DISSOLVED IN WATER THAT IS DESIGNATED BY MOLARITY.

Acids are always aqueous solutions, that is they are always dissolved in water. The concentration of an acid refers to the quantity of hydrogen ions that are present in the acid. If an acid contain a large quantity of hydrogen ion, it will be described as concentrated acid and if it contains a little quantity of hydrogen ion it will be described as diluted acid. The quantity of hydrogen ion [pH] in acids ranges from 1 to 6; 1 is very acid acidic and 6 is the least acidic.
