The Columns in the table that provides the information necessary for the calculating the mole ratio of Ca to Mg are columns ; 3, 4, 6, and 7

Although some data related to your question is missing attached below is the missing data

Determining the mole ratio of Ca to Mg

Ca : Mg

mass of Ca / molar mass : mass of Mg / Molar mass

( 36.1 / 40.1 ) : ( 2.4 / 24.3 )

9.14 : 1

∴ The mole ratio of Mg to Ca

≈ 1 : 9

Where: Column 3 = Mass of Mg in the sample ( g )

Column 4 = mass of Ca in the sample ( g )

Column 6 = Molar mass of Mg ( g/mol )

Column 7 = molar mass of Ca ( g/mol )

Hence the Mole ratio of Mg to Ca = 1 : 9
