Question

molecular mass of
K2 SO4 Al2 (SO4) . 24H2O
do it as fst as possible

Answer 1

Molar mass of K2SO4*Al2(SO4)3*24H2O is 948.7768 g/mol i.e. 950 g/mole approx.

Answer 2

Answer: The molecular mass of the given compound is 948 g/mol.

Explanation:

Molecular mass is defined as the sum of mass of individual elements constituting a compound.

The given molecular formula contains 5 elements: Potassium, aluminium, sulfur, oxygen and hydrogen. The molar mass of each of the elements are:

Hydrogen = 1 g/mol

Oxygen = 16 g/mol

Sulfur = 32 g/mol

Aluminium = 27 g/mol

Potassium = 39 g/mol

Molecular mass of the given compound:

$K_2SO_4.Al_2(SO_4)_3.24H_2O=[(2\times 39)+32+(4\times 16)+(2\times 27)+3(32+(4\times 16))+24((2\times 1)+16)]\\\\\text{Molecular mass of }K_2SO_4.Al_2(SO_4)_3.24H_2O=948g/mol$

Hence, the molecular mass of the given compound is 948 g/mol.
