    The mass of 1.72 mol of magnesium fluoride is 107 grams.

    To determine the mass of 1.72 mol of magnesium fluoride, we first need the chemical formula of magnesium fluoride. Magnesium forms a + 2 ion (Mg+2) and fluoride forms a - 1 ion (F-1). Since all compounds formed from ions have to be electrically neutral, we need 2 fluoride ions and 1 magnesium ion. Therefore, the formula for magnesium fluoride is MgF2.

    Now we need to determine the molar mass of the compound from the molar mass values from the periodic table. Let's use a table to calculate this molar mass.

    Molar mass of MgF2

    Element Molar Mass (g/mol) Quantity Total (g/mol)

    Mg 24.31 1 24.31

    F 19.00 2 38.00

    Total molar mass of MgF2 = 24.31 g/mol + 38.00 g/mol = 62.31 g/mol

    This is the mass of one mole of the substance. If we have 1.72 mols of it, we multiply 1.72 by 62.31.

    1.72 mol (62.31 g/mol) = 107 grams

    We rounded to 107 to keep the correct number of significant digits in our answer.
