swat32

Answer:

\large \boxed{\text{1.52 g}}

Explanation:

1. Calculate the moles of CoF₂ needed

n = \text{0.100 L} \times \dfrac{\text{0.157 mol}}{\text{1 L}}  = \text{0.0157 mol}

2. Calculate the mass of CoF₂

m = \text{0.0157 mol} \times \dfrac{\text{96.93 g}}{\text{1 mol}}  = \text{1.52 g}\\\\\text{ The student must measure out $\large \boxed{\textbf{1.52 g}}$ of cobalt(II) fluoride}

Purpose of boiling chip
vichka [17]
Your attempted answer is correct.
Indeed, certain liquids, including water, could superheat when heated in a perfectly smooth container.  The superheating could be interrupted by the minutest speck of dust or impurities causing a mass conversion into steam, observed physically as a bumping, causing splashes and endangering operators.  Boiling chips introduce these interruptions constantly and ensure a smooth boiling of the liquid.
