Answer:

47730 grams.

Explanation:

First we convert 1.752x10²⁶ formula units of Ca(NO₃)₂ into moles, using Avogadro's number:

  • 1.752x10²⁶ formula units ÷ 6.023x10²³ 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
