Molar mass of acetone (CH_{3}) _{2} CO is 58.07914 g/mol

Elements presents in acetone is

Carbon, Hydrogen and Oxygen

Atomic mass of carbon is = 12.01 u

Atomic mass of Hydrogen = 1..00 u

Atomic mass of Oxygen = 15.99 u

So molar mass of acetone will be

= (CH_{3}) _{2} CO

= ( 12.01 + 3*(1.00))*2 + 12.01 + 15.99

=58.07914 g/mol

Table Giving Answer

Element Atomic mass % Amount

Mg_24     24                79    18.96

Mg_25 25                10    2.5

Mg_26 26                11   2.86

   

Total                     24.32

Discussion

The method of calculation for this table, which was done in Excel (a spread sheet) is shown below. Assume that there is 100 grams of material of "pure" magnesium. What is it's mass?

<em><u>Sample  Calculation</u></em>

The the sample atomic mass = 24

Mass = % * sample atomic mass

Mass = 79% * 24

Mass = (79/100) * 24

Mass = 18.96

<em><u>Note</u></em>

The other two elements are found exactly the same as the sample calculation.

Then all you do is add the 3 masses together.

Answer

The mass of Mg to 1 decimal place is 24.3 <<<< Answer.
