Question

Calculate the molar mass of CaCOH.

Answer 1

Explanation:

Molar mass of CaCOH: 69.0957 g/mol

Further explanation

The elements in nature have several types of isotopes

Isotopes are atoms whose atomic number has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

So the atomic mass is obtained is the mass of the atom relative to the 12th carbon atom

Atomic mass X = isotope mass 1.% + isotope mass 2.%

An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.

The 'amu' unit has now been replaced with a unit of 'u' only

In stochiometry therein includes

Relative atomic mass (Ar) and relative molecular mass / molar mass (M)

So the molar mass of a compound is given by the sum of the relative atomic mass of Ar

Atomic weight (Ar) of

Ca: 40.078 g/mol

C : 12.0107 g/mol

O : 15.999 g/mol

H : 1.008 g/mol

molar mass of CaCOH

molar mass = Ar Ca + Ar C + Ar O + Ar H

Answer 2

Atomic mass of Ca=40u

Atomic mass of C=12u

Molar mass of OH =17u

So 40u+17u+12u=69 u
