Answer:
Explanation:
First, calculate the molar mass of NH4SO2. The molar mass can determine the number of moles. Then use Avogadro's number to calculate the number of molecules.
Key Steps:
Step 1. Calculate the molar mass of your compound
Step 2. Divide 2.3 grams by the molar mass of NH4SO2, this gives us moles
Step 3. Multiply by Avogadro's number (6.02x10^23) this gives you molecules.
