Calculate the percent composition of chlorine in NaCI a. Step 1: b. Step 2: Solution: __

## Step 1:<br />To calculate the percent composition of chlorine in NaCl, we first need to find the molar mass of each element in the compound. The molar mass of an element is the mass of one mole of that element.<br /><br />### The molar mass of Sodium (Na) is approximately 22.99 g/mol.<br />### The molar mass of Chlorine (Cl) is approximately 35.45 g/mol.<br /><br />## Step 2:<br />Next, we add the molar masses of Sodium and Chlorine to get the molar mass of the compound NaCl.<br /><br />### The molar mass of NaCl = Molar mass of Na + Molar mass of Cl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol.<br /><br />## Step 3:<br />Finally, we calculate the percent composition of Chlorine in NaCl by dividing the molar mass of Chlorine by the molar mass of NaCl and then multiplying by 100.<br /><br />### The percent composition of Chlorine in NaCl = (Molar mass of Cl / Molar mass of NaCl) * 100 = (35.45 g/mol / 58.44 g/mol) * 100 = 60.66%.
