To find the number of molecules in 230 grams of NH4OH, we need to follow these steps:1. Calculate the molar mass of NH4OH.2. Convert the given mass of NH4OH to moles.3. Use Avogadro's number to find the number of molecules.Step 1: Calculate the molar mass of NH4OH.The molar mass of NH4OH is the sum of the molar masses of its constituent atoms:Molar mass of NH4OH = (1 × 14.01) + (4 × 1.01) + (16.00) + (1.01) = 35.05 g/molStep 2: Convert the given mass of NH4OH to moles.Given mass of NH4OH = 230 gramsMoles of NH4OH = Given mass / Molar massMoles of NH4OH = 230 g / 35.05 g/mol = 6.56 molesStep 3: Use Avogadro's number to find the number of molecules.Avogadro's number = 6.022 × 10^23 molecules/molNumber of molecules = Moles × Avogadro's numberNumber of molecules = 6.56 moles × 6.022 × 10^23 molecules/mol = 3.96 × 10^24 moleculesTherefore, there are approximately 3.96 × 10^24 molecules in 230 grams of NH4OH.
