    Answer:

    47730 grams.

    Explanation:

    First we convert 1.752×10²⁶ formula units of Ca(NO₃)₂ into moles, using Avogadro’s number:

    • 1.752×10²⁶ formula units ÷ 6.023×10²³ formula units/mol = 290.88 mol

    Then we convert 290.88 moles of Ca(NO₃)₂ into grams, using the molar mass of Ca(NO₃)₂:

    • 290.88 mol * 164.088 g/mol = 47730 g
