How many moles are in 68 grams of Mg(OH)

1.16 mol

Explanation:

Given data:

Mass in gram Mg(OH)₂ = 68 g

Number of moles of Mg(OH)₂ = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of Mg(OH)₂ = 58.32 g/mol

By putting values,

Number of moles = 68 g/ 58.32 g/mol

Number of moles = 1.16 mol

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
