Question

How Many Moles Are Present In 50g Of Magnesium trioxide Carbonate iv

Answer 1

Answer:

1.8 moles

Explanation:

The chemical formula for magnesium trioxocarbonate(IV) is MgCO₃.

The number of moles of oxygen present in one mole of magnesium trioxocarbonate(IV) is three.

The molar mass(M) of MgCO₃ = ( 24×1) + (12×1) + (16×3) =84g.

Number of moles = \frac{Given mass}{Molar Mass}MolarMassGivenmass

Given mass = 50g

Number of moles = \frac{50}{84}8450

=0.6moles

The number of moles of oxygen = 0.6 ×3= 1.8

1.8 moles of oxygen are present in  50g of magnesium trioxocarbonate(IV).
