Answer 2

Given :

Formula of compound :

$Sc(OH)_3 \:$

To find :

Gram formula mass of compound.

Solution :

Gram formula mass (gfm) of a compound is the amount of a compound that has the same mass in grams as the formula mass in atomic mass unit.

An atom of each element has a characteristic mass and similarly each molecule of a compound has a characteristic formula mass.

When the formula mass of an ionic compound is determined by adding its component atomic masses and expressed in grams, it is called the Gram Formula Mass.

GFM of Scandium (Sc) = 44.96 gram per mole

GFM of Oxygen (O) = 16.00 gram per mole

GFM of Hydrogen (H) = 1.01 gram per mole

So

GFM of compound :

$= 44.96 + (3 \times 16) + (3 \times 1.01) \\ = 44.96 + 48 + 3.03 \\ = 95.99$

So,

GFM of compound = 95.99 gram per mole.
