To find the number of molecules in 2.3 grams of
, we need to follow these steps:1. Calculate the molar mass of
.2. Convert the given mass of
to moles.3. Use Avogadro's number to find the number of molecules.Step 1: Calculate the molar mass of
.The molar mass of
is calculated by adding the molar masses of each element in the compound:
Molar mass of
Step 2: Convert the given mass of
to moles.Given mass of
Moles of
Step 3: Use Avogadro's number to find the number of molecules.Avogadro's number =
Number of molecules =
Therefore, there are approximately
molecules in 2.3 grams of
.
