Molar Mass Conversion Factors Help

The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol. To see why these elements have different molar masses, we need to remember that the atoms of different elements contain different numbers of protons, neutrons, and electrons, so they have different masses. The atomic masses given in the periodic table inside the front cover of this book represent the different weighted average masses of the naturally occurring atoms of each element. Different atomic masses lead to different molar masses.

For example, the atomic mass of magnesium (24.3050) shows us that the average mass of magnesium atoms is about twice the average mass of carbon atoms (12.011), so the mass of 6.022 x 1023 magnesium atoms (the number of atoms in 1 mole of magnesium) is about twice the mass of 6.022 x 1023 carbon atoms (the number of atoms in 1 mole of carbon). Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbon’s molar mass of 12.011 g/mol.

The number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the element.

For example, the atomic mass of the element neon listed on the periodic table on the inside cover of this book is 20.1797, giving a molar mass of 20.1797 g/mol. This measurement provides the following conversion factors for converting between grams and moles of neon.

How many moles of Mg₃(PO₄)₂, will contain 0.25 mole of oxygen atoms?

How Many Moles Of Mg3 Po4 2 Will Contain 0 25 Mole Of Oxygen Atoms

How many moles of Mg 3 (PO 4 ) 2 , will contain 0.25 mole of oxygen atoms?

We have to determine the number of moles of Mg 3 (PO 4 ) 2

Solution

1 mole of Mg 3 (PO 4 ) 2 (molecule) contains:

3 moles of Mg atoms

2 moles of P atom

8 moles of O atoms.

1 mole of Mg 3 (PO 4 ) 2 (molecule) contains 8 moles of oxygen atoms

Thus x moles will contain – 0.25 moles of oxygen atoms

On cross multiplying we get

0.25 X 1 = 8x

x= 0.25/8

x= 3.125 x 10-2

x= 0.03125 moles.

Answer

The number of moles of Mg 3 (PO 4 ) 2 = 0.03125 moles.
