Answer: D) g
Explanation: The question asks to convert formula unit to grams. It is a unit conversion problem.
1 mole equals to Avogadro number of formula units. So, to convert the given number of formula units to moles, we need to divide by the Avogadro number. After this, we do moles to grams conversion and for this the moles are multiplied by the molar mass of the compound. Molar mass of AgCl is 143.32 gram per mol.
= g
So, the correct option is D) g
1) Carbon dioxide is a gas, so when is evolved in the reaction, it appears as bubbles. The gas released extinguishes the fire and it can turn lime water milky.
