What is the molar mass of AlCl3? A. 62.43 g/mol
B. 116.39 g/mol
C. 124.86 g/mol
D. 133.33 g/mol
E. 187.29 g/mol

133.33 g/mol

Explanation:

Molar mass:

Molar is the sum of all the atomic masses of the atoms of the elements present in a compound.

Molar mass of AlCl₃:

Atomic mass of Al = 26.98 amu

Atomic mass of chlorine = 35.45 amu

There are 3 atoms of chlorine present.

35.45×3 = 106.35

Molar mass of AlCl₃ = 26.98  + 106.35  = 133.33 g/mol

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
