To find the mass in grams of
molecules of
, we need to follow these steps:1. Determine the molar mass of
.2. Calculate the number of moles of
using Avogadro's number.3. Multiply the number of moles by the molar mass to find the mass in grams.Step 1: Determine the molar mass of
.The molar mass of chlorine (Cl) is approximately 35.45 g/mol. Since
consists of two chlorine atoms, the molar mass of
is:
Step 2: Calculate the number of moles of
using Avogadro's number.Avogadro's number is
molecules/mol. To find the number of moles, we divide the given number of molecules by Avogadro's number:
Step 3: Multiply the number of moles by the molar mass to find the mass in grams.
Therefore, the mass of
molecules of
is approximately 23.50 grams.
