Answer:

2365.0 g

Explanation:

First we convert 1.2 x 10²⁵ particles into moles, using Avogadro's number:

  • 1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol

Then we convert 19.9 moles of NiCO₃ into grams, using the molar mass of NiCO₃:

  • NiCO₃ Molar Mass = 118.702 g/mol
  • 19.9 mol * 118.702 g/mol = 2365.0 g
