Magnesium hydroxide (Mg(OH)2): g/mol Iron(III) oxide (Fe2O3): g/mol

steposvetlana [31]

Molecular mass of Mg(OH)2

= Atomic mass of Mg + 2(Atomic mass of O) + 2(Atomic mass of H)

= 24 g/mol + 2(16 g/mol) + 2(1 g/mol )

= 58 g/mol

Molecular mass of Fe2O3

= 2(Atomic mass of Fe) + 3(Atomic mass of O)

= 2(56 g/mol) + 3(16 g/mol)

= 160 g/mol

The distance between a carbon atom and an oxygen atom in the co molecule is how far from the carbon atom is the center of mass o

DENIUS [597]

The distance between a carbon atom and an oxygen atom in the co molecule is 0.63

<h3>What is the distance?</h3>

Distance is the measurement of the farness of two objects from each other.

The distance between the molecules can be calculated by the given formula

$xcm = m_1+m_2m_1\times 1+m_2 \times 2$

Putting the values in the equation

$xcm = 12+1612 \times 0+16 \times 1.1 = 0.63 A^\circ$

Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63
