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
