Multiple Choice 1 point What is the molar mass of Mg(NO_(3))_(2) 148.33g/mol 84.33g/mol 132.33g/mol 110.01g/mol

The molar mass of $Mg(NO_{3})_{2}$ is $148.33g/mol$. This is calculated by adding the molar masses of each individual atom in the compound: Magnesium (Mg) has a molar mass of 24.305 g/mol, Nitrogen (N) has a molar mass of 14.007 g/mol, and Oxygen (O) has a molar mass of 15.999 g/mol. Since there are two Nitrogen atoms and six Oxygen atoms in the compound, the total molar mass is calculated as follows: 24.305 g/mol (Mg) + 2 * 14.007 g/mol (N) + 6 * 15.999 g/mol (O) = 148.33 g/mol.
